How Operation Sindoor prompted air raid siren revamp in Mumbai and beyond
Air raid sirens, which once acted as sentinels of Mumbai and its surroundings, are set to be revived in the aftermath of Operation Sindoor, India's military response to Pakistan after the terror attack in Pahalgam last month.The state has 492 air raid siren points in all—311 in Mumbai, 85 in Pune, 33 in Nashik, 21 in Tarapur, 16 in Raigad and 26 in Thane. These were installed in phases after the 1962 India-China war, as per central government guidelines, and came in handy for sounding air raid warnings during the wars with Pakistan in 1965 and 1971. Even later, the sirens would be sounded at 9 am every day.advertisementMany of these public sirens, including some in Mumbai, are now dysfunctional. The centrally-operated system gradually went into oblivion after 2004 due to technological obsolescence. The torrential rain-triggered flooding of the Mumbai region in 2005 also damaged some underground cables that connected these sirens. The last time the air raid sirens were sounded was in July 2006 to pay tributes to the victims of serial bomb blasts in suburban trains in Mumbai.The technological obsolescence has meant each siren is to be operated manually, and the decentralised nature of these operations made it difficult for government agencies to verify if these civil defence sirens, especially those in non-governmental premises, were working. However, some sirens installed on government buildings such as Cross Maidan and the Directorate office at Kalaghoda are tested regularly.advertisement
On May 7, the union home ministry had issued an advisory to all states and Union territories for undertaking mock drills. This included the operationalisation of air raid sirens. Sources said that only 50 to 60 sirens in Mumbai were found to be working, and of the 492 sirens in the state, around 50 per cent were functional.These sirens are now being revived as part of efforts to sound emergency alerts and prepare for a war-like scenario in the future. Yogesh Kadam, Maharashtra minister of state for home, told INDIA TODAY that the government had sought a proposal from the Directorate of Civil Defence for upgrade of these sirens. 'This is an old system and we will upgrade it,' he said.Prabhat Kumar, director general of police and director of civil defence, Maharashtra, said they were working on reviving and strengthening the existing sirens in Mumbai and the coastal districts of Palghar, Thane, Raigad, Ratnagiri and Sindhudurg. Newer sirens were also being installed in the legacy network.'On the instructions of chief minister Devendra Fadnavis, the state government has provided funds as per the provisions of the Civil Defence Act, 1968, and Disaster Management Act, 2005 We will have a minimum of 100 sirens in good condition in Mumbai, and in vital areas like Uran and Tarapur,' said Kumar.advertisementHe stated that procurement of these sirens and their installation were underway. Apart from bolstering the traditional sirens, the directorate is also planning to procure and install a state-of-art system in the future.While Tarapur, located around 130 km from Mumbai in Palghar district, has a nuclear power plant—the Tarapur Atomic Power Station—Uran in Raigad district is located in proximity to sensitive installations such as the Jawaharlal Nehru Port Trust, an Oil and Natural Gas Corporation plant and a gas thermal power station operated by the Maharashtra State Power Generation Company.However, officials said that using air raid sirens came with its own set of challenges in a heavily built-up city like Mumbai, where much had changed since the times these sirens had been originally installed. 'The highrise buildings in Mumbai act as sound barriers for traditional sirens. The glass faade on these buildings does not allow the sound to penetrate deep. The ambient noise in the city is also high,' an official said.The civil defence mechanism has its roots in the 'Air Raid Precaution Committee', which was established in August 1937 in the run-up to World War II. In October 1939, air raid precaution wardens were enrolled for the first time in Bombay. In October 1941, air raid precaution was redesignated as civil defence.advertisementSubscribe to India Today MagazineTune InMust Watch

Trial in 2020 Delhi riots larger conspiracy case delayed again after judge's transfer
The trial in the larger conspiracy case related to the 2020 Delhi riots has been delayed again following the recent reshuffle of 135 judges in courts of the national capital, The Indian Express reported. The case was at the stage of arguments on charges. The trial was expected to begin after the arguments were heard. Five of the 18 persons accused in the matter had completed their arguments, the newspaper reported. They will have to present their arguments before the court again. The special public prosecutors, who had also completed their arguments on behalf of the Delhi Police, will also have to present their arguments again. This is the second time that the case has been delayed because of a routine transfer of the judge, The Indian Express reported. On Monday, Additional Sessions Judge Lalit Kumar of the Karkardooma court directed the special public prosecutors and counsels of the persons accused in the case to submit their schedule relating to the timeframe and the manner in which they will present their arguments, especially the time to be taken by them, Bar and Bench reported. The matter will be heard next on Friday. Kumar assumed charge as the judge on May 30 after the reshuffle in the Delhi district judiciary. The earlier arguments in the case, which began in September, had taken place before the previous judge Sameer Bajpai. Clashes had broken out in North East Delhi in February 2020 between supporters of the Citizenship Amendment Act and those opposing it. The violence left 53 dead and hundreds injured. The Delhi Police has claimed that the violence was part of a larger conspiracy to defame the Narendra Modi government and was plotted by those who organised the protests against the contentious citizenship law. Eighteen persons have been booked under sections of the Unlawful Activities Prevention Act and the Indian Penal Code. The persons include activists Umar Khalid, Sharjeel Imam, Natasha Narwal, Meeran Haider Tahir Hussain and Ishrat Jahan, and Shifa-Ur-Rehman.

Bilawal Bhutto's Rant On Indian Muslims Backfires, Reporter Cites Op Sindoor Unity Briefing
Last Updated: Bilawal Bhutto-Zardari's anti-India claims at the UN were countered by a journalist who cited an Indian Muslim officer leading Operation Sindoor, leaving Bilawal with no response. Pakistan's former foreign minister Bilawal Bhutto-Zardari, while speaking at a press conference at the UN headquarters in New York on Tuesday, made a rash attempt to push an anti-India narrative as he claimed that 'Muslims were being demonised" in the country. However, his anti-India propaganda was effectively countered by a foreign journalist, who pointed out that he had personally witnessed India's Operation Sindoor briefing being headed by an Indian Muslim officer. The journalist's remarks visibly left Bilawal with no counter, and he simply nodded in response. At UN, Bilawal Bhutto claimed that Indian Govt is demonising muslims in India after Pahalgam Terror attack in Kashmir.A foreign Muslim Journalist replied that as far as he recalls Indian muslim military official was conducting the briefing for India's Operation Sindoor.… — Incognito (@Incognito_qfs) June 4, 2025 Operation Sindoor's briefing was led by two senior women officers: Colonel Sofiya Qureshi of the Indian Army's Corps of Signals and Wing Commander Vyomika Singh, a helicopter pilot in the Indian Air Force, along with Foreign Secretary Vikram Misri. 'As far as the hurdles we face within the UN and in general, as far as the Kashmir cause is concerned, that still exists," Bilawal Bhutto said at the press conference. Currently, Bilawal Bhutto is heading a parliamentary delegation to the United States which has been given the task of presenting Islamabad's narrative on recent regional tensions. While speaking with UN officials and diplomats, Bhutto said that subjects like water disputes and terrorism had some reception. The structure of the Pakistani delegation is very similar to India's recent diplomatic offensive, in which an all-party parliamentary delegation has been constituted, which is travelling across the present New Delhi's position after the Pahalgam massacre. After arriving in New York on Monday, Bilawal Bhutto's delegation held meetings with UN Secretary-General António Guterres, General Assembly President Philemon Yang, and Security Council President Carolyn Rodrigues-Birkett. They also interacted with the permanent representatives of the United States, China, Russia, and France, along with four other permanent members of the Security Council and the representatives from non-permanent member states. The Pakistani delegation on Wednesday is scheduled to be in Washington, DC, at the same time when the Indian delegation led by senior Congress MP Shashi Tharoor will be present there.
