Watch live: Iran fires missiles at Israel, residents told to shelter in place

JERUSALEM - The Israeli military said Tuesday that Iran has fired missiles at Israel, and air raid sirens sounded across the country as residents were ordered to remain close to bomb shelters.

The alerts were sounded after a day of rocket and missile attacks from Lebanon, and as Israel said it had begun limited ground operations in southern Lebanon. Israeli airstrikes and artillery fire pounded southern Lebanese villages where people were ordered to evacuate, and Hezbollah militants responded by firing a barrage of rockets into Israel.

Iran had launched an unprecedented direct attack on Israel in April, but few of its projectiles reached their targets. Many were shot down by a U.S.-led coalition, while others apparently failed at launch or crashed in flight.
