Unidentified drones were reported near Fort Lesley J. McNair in Washington, D.C., as the U.S. has heightened security at military installations amid strikes on Iran.

Iran war: What is happening on day 19 of US-Israel attacks? Iran has pledged "revenge" after Israeli strikes killed security chief Ali Larijani and commander of Basij paramilitary forces Gholamreza Soleimani, with Foreign Minister Abbas Araghchi saying Tehran's political system remains strong as the war entered its 19th day . Iran launched more attacks on Israel, causing extensive property damage, after an earlier strike killed two people in Ramat Gan. Political tensions are also rising in the United States, as senior counterterrorism official Joe Kent resigned, saying "we started this war due to pressure from Israel and its powerful American lobby". Meanwhile, President Donald Trump criticised NATO allies and partners for failing to provide stronger military support in efforts to end Iran's chokehold on the Strait of Hormuz.

Iran has fired missiles and drones at several Gulf Arab nations, which have sought to intercept them, in a now-daily fallout from the United States-Israel war launched on Iran nearly three weeks ago that has engulfed the Middle East with deaths, destruction, assassinations, and an energy crisis spreading far beyond the region. Early Tuesday, Qatar's Ministry of Defence said its armed forces intercepted a missile attack against the country. The statement came hours after the Kuwaiti army said it was intercepting hostile missile and drone attacks. The UAE, Saudi Arabia and Bahrain have also reported intercepting missiles and drones in recent hours. Saudi Arabia's Ministry of Defense reported the interception and destruction of a drone in the Eastern Region.

Over 200 Ukrainian military experts in Gulf region to counter Iran's drones More than 200 Ukrainian military experts are in the Gulf region and wider Middle East helping governments in their defence against Iran's drone attacks, Ukraine's President Volodymyr Zelenskyy has said. In an address to dozens of members of the United Kingdom Parliament in London on Tuesday, the Ukrainian leader said 201 Ukrainian anti-drone experts are in the region and another 34 "are ready to deploy". "Our teams are already in the Emirates, Qatar, Saudi Arabia, and on the way to Kuwait," the Ukrainian leader said. "We are working with several other countries - agreements are already in place. We do not want this terror of the Iranian regime against its neighbours to succeed," he said.

The BBC has obtained footage and interviews from the Iranian capital Tehran which evoke a city of strained nerves, of constant waiting for the next air strike and relentless fear of the state security apparatus. The identities of the people in this report have been protected. While independent journalists still try to gather testimony that offers a credible alternative view, they run the risk of arrest, torture and possibly worse. Displaced Palestinians were told to secure their tents to prevent them being blown away as a storm swept through the enclave. Video filmed by a witness and verified by the BBC shows a drone crashing close to the airport.

Where OpenAI's technology could show up in Iran Three places to watch, from the margins of war to the center of combat. It's been just over two weeks since OpenAI reached a controversial agreement to allow the Pentagon to use its AI in classified environments. There are still pressing questions about what exactly OpenAI's agreement allows for; Sam Altman said the military can't use his company's technology to build autonomous weapons, but the agreement really just demands that the military follow its own (quite permissive) guidelines about such weapons. OpenAI's other main claim, that the agreement will prevent use of its technology for domestic surveillance, appears equally dubious . It's not the first tech giant to embrace military contracts it had once vowed never to enter into, but the speed of the pivot was notable. Perhaps it's just about money; OpenAI is spending lots on AI training and is on the hunt for more revenue (from sources including ads).

Hundreds of passengers flying to Dubai spent 11 hours on a flight to nowhere after their plane was turned back over Egypt. The Emirates flight EK24 set off from Edinburgh at 21:26 on Sunday and was due to land in Dubai at 06:49 on Monday. However, as the plane flew over Egypt, flights at Dubai International Airport were suspended following a fire caused by an Iranian drone hitting a fuel tank. The plane was forced to return to Edinburgh. Travel journalist Simon Calder told the BBC's Radio Scotland Breakfast programme that although Dubai was on the UK Foreign Office's No go list, many people were still taking the risk of flying there. No injuries were reported following the drone strike but officials said they had taken all necessary measures to ensure public safety.

Could Iran be using China's BeiDou system? Iran war: What is happening on day 17 of US-Israel attacks? Israel launched a new wave of attacks on Tehran as the US-Israel war on Iran entered its 17th day on Monday. Escalations continue in the Gulf region, where authorities suspended flights at Dubai international airport after a drone incident sparked a fire nearby.

Could Iran be using China's BeiDou system? The United Arab Emirates (UAE) has announced diversion of some flights from the Dubai international airport, one of the world's busiest, after a drone attack sparked a fire near the facility, as Bahrain, Kuwait, Qatar and Saudi Arabia also reported intercepting drones and missiles. The Dubai Media Office on Monday said civil defence teams had "successfully contained the fire resulting from impact to one of the fuel tanks in the vicinity" of the airport, noting that no injuries had been reported so far. The Dubai Civil Aviation Authority, meanwhile, said it was temporarily suspending flights at the airport "as a precautionary measure to ensure the safety of all passengers and staff". It did not say when they expected flights to resume.
