Iran launches massive drone and missile attack against Israel

JERUSALEM — Iran launched a massive attack of more than 300 missiles and drones toward Israel late Saturday, a stunning assault that put the Israeli military on high alert and threatened to unleash more violence in an already turbulent region.

Interceptions by Israel’s sophisticated air and missile defense systems began overnight, causing loud booms over Jerusalem and air raid sirens to sound across the country. The military warned citizens to brace for an attack of undetermined scale, as combat aircraft filled the sky over much of Israel. Officials closed schools and banned large gatherings as some airports in the region halted operations.
