Satellite imagery reveals damage to key Iran nuclear sites
Satellite imagery shared with BBC Verify has provided a clearer picture of damage inflicted on two of Iran's key nuclear sites as well as other military targets.
Imagery from two different providers shows damage to the Natanz nuclear facility as well as a missile site south of the city of Tabriz - hit in the first round of strikes against Iran on Friday.
Other images show damage to other known missile bases.
Israel is continuing to target numerous sites across Iran, which has prompted retaliatory strikes.
Newly released optical satellite imagery from Maxar shows the clearest picture yet of what happened at key Iranian nuclear sites at Natanz and Isfahan.
At Natanz, we can see damage to the pilot fuel enrichment plant and an electrical substation, according to analysis by the Institute for Space and International Security (ISIS).
This follows on from earlier analysis of radar imagery that first showed the damage.
On Friday the head of the International Atomic Energy Agency, Rafael Grossi, told the UN Security Council that "the above-ground part of the pilot fuel enrichment plant, where Iran was producing uranium enriched up to 60% U-235, has been destroyed".
Uranium-235 is essential both for nuclear power stations and also for nuclear weapons.
Verified footage taken shortly after the strikes show several plumes of smoke rising from the site.
Justin Bronk of the Royal United Services Institute (RUSI), told BBC Verify that, while inconclusive, the pattern of explosions "would fit with penetrating bombs being used. Probably GBU-31(V)3s or even possibly more specialised penetrating GBU-28s".
These munitions, known as "bunker busters", have been used by Israel in the past to target underground facilities in both Gaza and Lebanon.
However, Mr Grossi said there is "no indication of a physical attack on the underground cascade hall containing part of the pilot fuel enrichment plant and the main fuel enrichment plant".
On Saturday, the IAEA confirmed that four "critical buildings" were damaged at Isfahan, including the Uranium conversion facility and the fuel plate fabrication plant.
BBC Verify analysis of the latest images from Maxar found visible damage to at least two structures at Isfahan and an apparent scorch mark near the periphery of the site.
The IAEA has said that "no increase in off-site radiation" has been recorded at either Natanz or Isfahan.
Maxar also provided imagery from two other key Iranian nuclear sites which showed no visible evidence of damage, specficially the the Arak heavy water reactor or the Fordow enrichment facility.
Iranian media had reported the latter site was targeted, but the IDF have since denied this.
Imagery and analysis captured on Friday by Umbra Space reveals damage to several parts of a missile complex near the city of Tabriz in north-western Iran.
The damaged sites include weapon storage areas, missile shelters and silos, according to the annotated graphic provided by Umbra with analysis by geospatial intelligence consultant Chris Biggers.
In Kermanshah, low resolution imagery from Planet Labs shows what appears to be extensive burn marks to an area near a known missile base, and possible damage to two buildings.
Footage we verified from the same site on Friday showed at least three large plumes of smoke rising from the base.
Maxar also provided imagery showing significant damage to one structure at Iran's Islamic Revolutionary Guard Corps (IRGC) Ghadir ballistic missile base near Tehran, and considerable damage to the IRGC radar site in Piranshahr in West Azerbaijan Province.

The secretive Iranian nuclear site that's a key target for Israel
It's key to Iran's nuclear program: the Fordow plant - in a mountain lair where hundreds of centrifuges, hidden possibly 90 meters underground, enrich uranium to 60%. CNN's Nick Paton Walsh explains what we know about the key site in Israel's crosshairs.

Nuclear chief warns of contamination at Iran's main atomic site
VIENNA -- The head of the International Atomic Energy Agency said Monday that there is a possibility of both radiological and chemical contamination within Iran's main nuclear enrichment facility in Natanz following Israeli strikes, although radiation levels outside the complex are presently normal. IAEA director general Rafael Mariano Grossi said that the radiation poses a significant danger if uranium is inhaled or ingested. He added that the risk can be effectively managed with appropriate protective measures, such as using respiratory protection devices while inside the facilities. 'The level of radioactivity outside the Natanz site has remained unchanged and at normal levels, indicating no external radiological impact to the population or the environment from this event,' Grossi said. Grossi was addressing an urgent session of the U.N. nuclear watchdog board in Vienna that was convened at the request of Russia to discuss Israeli attacks against Iranian nuclear facilities. He said there apparently was no additional damage at Natanz and the Isfahan nuclear research site since Saturday. He said that the main concern inside the Natanz facility is the chemical toxicity of a gas called uranium hexafluoride, which is the result of fluorine mixed with the uranium during enrichment. It is extremely volatile, will quickly corrode, can burn the skin and is especially deadly if inhaled, experts say. 'Amid theses challenging and complex circumstances, it is crucial that the IAEA receives timely and regular technical information about the facilities and their respective sites,' Grossi said. Without information, the U.N. nuclear watchdog 'cannot accurately assess the radiological conditions and potential impacts on the population and the environment and cannot provide the necessary assistance.' Grossi said that U.N. inspectors will remain present in Iran and inspect the nuclear facilities 'as soon as safety conditions allow.' He warned that 'military escalation threatens lives, increases the chance of a radiological release with serious consequences for people and the environment and delays indispensable work towards a diplomatic solution for the long-term assurance that Iran does not acquire a nuclear weapon.' Satellite photos analyzed by The Associated Press show extensive damage at Iran's main nuclear enrichment facility in Natanz. The images captured Saturday by Planet Labs PBC show multiple buildings damaged or destroyed. The structures hit include buildings identified by experts as supplying power to the facility. Grossi told the U.N. Security Council on Friday that the above-ground section of the Natanz facility was destroyed. The main centrifuge facility underground did not appear to be hit, but the loss of power could have damaged infrastructure there, he said. Israel also struck a nuclear research facility in Isfahan. The IAEA said four critical buildings were damaged, including an uranium-conversion facility, but there was no sign of increased radiation at Natanz or Isfahan. Grossi on Monday also told the IAEA board of governors that no damage has been seen at the site of the Fordo enrichment site, which is buried under a mountain and protected by anti-aircraft batteries. Fordo appears designed to withstand airstrikes. Grossi also said that the Bushehr nuclear power plant, Iran's only commercial nuclear power plant, has not been targeted nor affected by the recent attacks and neither has the Tehran Research Reactor. Any country on the 35-member board of the IAEA can call a meeting under its rules. The IAEA board last week found Iran in non-compliance with its nuclear obligations for the first time in 20 year.
