President Donald Trump announced in a Truth Social post late Saturday that the United States has launched strikes on three Iranian nuclear sites — inserting itself into Israel’s war against the country in a move that risks a wider war involving major global powers.In an address to the nation that lasted less than four minutes, the president gave virtually no explanation or rationale for striking the Fordo, Natanz and Esfahan nuclear sites. He also vaguely suggested deescalation, but declined to say how.“Iran, the bully of the Middle East, must now make peace,” Trump said. “If they do not, future attacks would be far greater and a lot easier.”For two decades, HuffPost has been fearless, unflinching and relentless in pursuit of the truth.

Some lawmakers have called for a vote under the War Powers Act, which limits military action without congressional approval.Countries around the world are calling for diplomacy following the attack, but Iran’s foreign minister said the U.S. “crossed a very big red line” that has erased the possibility of diplomatic talks.Read our previous coverage here, and see the latest politics updates below:Qatar, Home Of Air Based Used By U.S. Forces, Closes AirspaceQatari officials announced Monday that it has closed its airspace amid Iranian threats of retaliation for Trump’s strike.The move is significant because Qatar is the home of Al Udeid Air Base, which is used by U.S. Central Command as its forward headquarters and houses some 10,000 American troops, along with British and Qatari military forces.The base, located southwest of Doha, is one of several housing U.S. troops in the Middle East that could be targeted in a retaliatory attack.Following an order by the U.S. embassy recommending all U.S. nationals in Qatar shelter in place, the British embassy in Qatar issued a similar directive on Monday. A spokesperson for the Qatari Ministry of Foreign Affairs said that the embassies' warnings did not necessarily reflect any specific threat, but were precautionary, and noted the government is monitoring the situation closely.
