What are sleeper cells and why are the FBI on alert for them after Trump's strikes on Iran?
The United States has ramped up its monitoring of Iranian sleeper cells as President Donald Trump's strikes on three major Iranian nuclear sites decisively propelled the U.S. into Israel's war.
Following Saturday's strikes, which Trump claimed 'totally obliterated' Iran's nuclear sites of Fordow, Natanz and Isfahan, both White House and FBI officials have been on high alert for Iranian sleeper cells.
Sleeper cells comprised of spies or terrorists hiding out in the U.S. or Western countries, remain inactive, often living quiet and unassuming lives working regular jobs until they are ordered to act on a mission. (Think Philip and Elizabeth Jennings, the fictional Cold War-era KGB spies who pose as the typical American couple with kids in suburban DC in FX's series The Americans.)
According to reports, Iran may now try to activate these covert spies after the U.S. joined Israel's strikes against Iran.
Even before Trump ordered U.S. involvement in the strikes, FBI Director Kash Patel increased efforts to surveil potential sleeper agents linked to Hezbollah – a U.S.-designated terror organization backed by Iran, sources told CBS News.
The increased surveillance started earlier this month, after Israel's Operation Rising Lion offensive began, according to the report.
Both current and former administrations have worried about the threat of Iranian operatives, especially after Trump ordered Iranian General Qasem Soleimani to be assassinated in January 2020.
In the wake of his killing, the FBI, Department of Homeland Security, and other agencies ramped up their resources to counter potential threats. Since then, prosecutors have also charged several U.S.-based individuals with plotting to kill both Trump and his national security adviser John Bolton.
A recent U.S. Department of Homeland Security threat assessment found that the intelligence community expects Iran to remain the primary source of terrorism and continue to advance plots against the U.S., according to NewsNation.
'As the conflict in the Middle East escalates and Iran is being targeted, the regime thinks to itself, 'OK, we are on our last throes, and therefore we will go out with a bang, quite literally,'' Barak Seener, a senior fellow at the Henry Jackson Society, told NewsNation before the U.S. joined the strikes.
'Its calculus will be very different if its survivability is threatened. Intelligence Services in the U.S. are working overtime to contend and mitigate risks and threats that can emerge on its domestic soil. The more protracted this conflict goes on, the heightened risk for both U.S. forces and assets in the Middle East, but also to U.S. security domestically,' Seener added.
United States Central Command officials have also said it is likely that the FBI is currently monitoring potential threats.
While the true extent of the damage from Saturday's strikes remains unclear, Iran has described the act as 'unforgivable' and vowed retaliation.
In wake of the attacks, Iran's foreign minister Abbas Araghchi accused Washington of having 'betrayed' negotiations over a nuclear deal.
Secretary of State Marco Rubio, however, cautioned Iran against any retaliation, echoing Trump's comments the night of the strikes, when the president posted: "There will either be peace or there will be tragedy for Iran far greater than we have witnessed over the last eight days."
Rubio said of Iran on Fox Business' "Sunday Morning Futures with Maria Bartiromo" that any such action against the U.S. or its interests would be "the worst mistake they've ever made."

Co-op to stop selling Israeli products and vows ‘to support peace'
Co-op will no longer sell products from Israel as part of a commitment to 'support peace'. The retailer said it has introduced the ban after coming under pressure from its members, with items such as carrots poised to be removed from shelves this month. It said the decision formed part of a wider push to 'stop sourcing relationships with countries where there are internationally recognised community-wide human rights abuses and violations of international law'. As well as boycotting Israeli produce, Co-op said it would also no longer stock products and ingredients from 16 other countries, including Russia, Iran and Syria. It follows a review of Co-op's sourcing policy, prompted by its members urging the retailer to 'do all it can to advocate and build peace'. Previously, Co-op did not source products from Israeli settlements in the Palestinian Occupied Territories, which include Gaza and the West Bank. However, it has been under pressure to go further, with members last month backing a motion for the board to boycott Israeli products altogether and show 'moral courage and leadership' on the issue. The Palestine Solidarity Campaign, a pressure group, said the vote by members meant the company should withdraw all Israeli produce, because it proved that Co-op members would not support Israel's 'apartheid economy'. On Tuesday, Debbie White, the Co-op chairman, said: 'As a business, we have a long-standing legacy of doing the right thing, supporting Fairtrade and championing ethical sourcing and this policy is a natural progression of this.' However, the boycott of Israeli produce is likely to spark fresh controversy, coming on the eve of Glastonbury, where Co-op is an official partner. The retailer operates a pop-up shop on the festival site, where it sells food and drink essentials. In recent weeks, festival organisers have come under fire for allowing pro-Palestinian campaigners to appear. This week, it emerged that a Palestine Action activist was poised to feature as a speaker at the festival, coming just hours after the Home Secretary banned the group under anti-terror laws. It follows a row over Glastonbury's decision to allow Kneecap to perform this weekend, amid pressure from artists for the festival not to censor the Irish republican hip-hop group. Glastonbury organisers have refused to bow to pressure to pull Kneecap from the line-up, despite one of the band members being charged for allegedly displaying a flag in support of the proscribed terrorist organisation Hezbollah. In footage, which is being assessed by the Metropolitan police, one member of Kneecap appears to say 'up Hamas, up Hezbollah' at a gig in November. Sir Keir Starmer last weekend said he did not think it was 'appropriate' for the group to perform at the festival.

‘A real fragility' to Iran and Israel ceasefire
The Tánaiste has said there was a 'a real fragility' to the ceasefire between Iran and Israel. Simon Harris said that a cessation in violence allows for diplomacy and dialogue. Advertisement However, just hours after a ceasefire was announced by US President Donald Trump, Israeli defence minister Israel Katz claimed Iran had 'completely violated' the agreement by launching missile strikes after it came into effect. The defence minister instructed Israeli forces to resume targeting Iranian paramilitary and government targets. Speaking in Dublin on Tuesday, Mr Harris said that any effort to de-escalate tensions is welcomed. He made the comments after returning from a meeting of EU foreign affairs ministers in Brussels, where they discussed the growing crisis in the Middle East. Advertisement Mr Harris said: 'We've been very clear at an Irish level and at a European level that the only way you bring safety and security to the region is through diplomacy, through dialogue and through de-escalation. 'Yesterday, when we had very extensive discussions in Brussels on this matter, we're very clear that Europe is ready to play a role in trying to help create that space for that sustained diplomacy. So we need to see regional stability, and we need to now see the ceasefire underpinned by sustained diplomacy. 'I think we obviously have to welcome the fact that there is a temporary ceasefire in place. That is a good thing. A cessation of violence, of hostilities, to allow space for diplomacy and dialogue is a good thing. But of course, there's a real fragility to this. We have updated our travel advice for Qatar 🇶🇦and UAE 🇦🇪. Qatar: UAE: Citizens in the region are encouraged to register at — DFATravelWise (@dfatravelwise) June 23, 2025 'At the moment, we have agreement for a temporary ceasefire. We hope that that turns into a permanent ceasefire, but that's what's in place at the moment. Advertisement 'I think what's really important now, and there isn't an hour to lose in relation to this, is that it is underpinned by that sustained diplomacy. And I certainly know from my engagement with the Jordanians, with the Saudis, with the Egyptians, with the Qataris yesterday, there's a real desire for that in the region. 'I know from extensive engagement at a European level, we believe Europe can play a very helpful role in relation to this. I would make the point that I made in Brussels yesterday, nobody wants to see Iran with nuclear weapons, but actually, the greatest progress that's ever been achieved in terms of keeping Iran away from nuclear weapons has been done through diplomacy, not through military aggression, and we need to get back to that dialogue now.' Mr Harris said he will convene a meeting of all ambassadors and embassy representatives from Middle Eastern countries on Tuesday afternoon. 'I want to get from them the very latest information on the ground in terms of our own Irish citizens, the presence of Irish people in the region,' he added. Advertisement 'The travel advice we put in place last night remains in place until it's updated. 'But we, obviously, as you can imagine, at this time, a great volatility, are reviewing, revising and monitoring that travel advice on an ongoing basis.'

Kremlin rejects charge it did little to help Iran
MOSCOW, June 24 (Reuters) - The Kremlin on Tuesday pushed back against criticism that it had not done enough to back Iran, saying it had taken a "clear position" by condemning U.S. and Israeli strikes on the Islamic Republic. President Vladimir Putin has condemned what he called "unjustified" U.S. attacks on nuclear sites in Iran, with which he signed a strategic cooperation treaty in January. He said on Monday that Russia would try to help the Iranian people, although he gave no specifics. Iranian sources told Reuters earlier this week that Tehran had not been impressed with Russia's support so far. Asked about comparisons to the toppling last year of Syrian leader Bashar al-Assad, when Moscow refused to send troops or more air power to keep its ally in power, the Kremlin said some people were trying to spoil the Russian-Iranian partnership. "Russia actually supported Iran with its clear position," Kremlin spokesman Dmitry Peskov said, adding that Iranian Foreign Minister Abbas Araqchi had appreciated Moscow's stance when he met Putin on Monday. It was still too early to assess the extent of the damage to Iran's nuclear facilities, Peskov said. "Some information is coming through the appropriate channels, but it is still too early," Peskov said. "Hardly anyone has a clear understanding right now." Asked about a Reuters report that Araqchi had brought a letter to Putin from Supreme Leader Ayatollah Ali Khamenei, Peskov said there had been no written document handed over. "The fact that there were certain messages from the Iranian leadership is true. But this Reuters report is not true," Peskov said. U.S. President Donald Trump announced on Monday a complete ceasefire between Israel and Iran, potentially ending the 12-day war that saw millions flee Tehran and prompted fears of further escalation in the war-torn region. "If it has really been possible to achieve a ceasefire, then this can only be welcomed," Peskov said, adding that Qatar had helped to broker the ceasefire. "This is what the Russian Federation has been calling for since the very beginning of this conflict. Therefore, yes, this can and should be welcomed, and we hope that this will be a sustainable ceasefire."
