Iran’s state broadcaster says U.S. and Israeli attacks have killed 787 people since Donald Trump joined Prime Minister Benjamin Netanyahu in a massive bombing campaign, striking 153 cities and more than 500 sites across Iran since Saturday. Much of the violence is directed at Iran’s capital Tehran, where thunderous explosions rang out for the third night in a row and into the daylight hours. Residents woke to scenes of widespread destruction, with city streets littered with debris from collapsed buildings. One attack hit Niloofar Square in eastern Tehran, flattening buildings and killing over 20 people. Drop Site News reports two explosions hit the area — a smaller strike followed by a larger “double tap” attack that devastated much of the neighborhood. On Monday, mourners in the city of Minab held a mass funeral for 165 schoolgirls and staff killed on Saturday, on the first day of the U.S.-Israeli strikes, when a missile struck a girls’ school.

Meanwhile, red alert sirens have been activated across much of Israel, with the Israeli military reporting missile interceptions over West Jerusalem, Tel Aviv and Eilat. On Monday, Ali Larijani, the secretary of the Iranian Supreme National Security Council, warned, “Iran, unlike the United States, has prepared itself for a long war.”
