“On this day, the day of our holiday, our enemies fired rockets into our communities,” Prime Minister Benjamin Netanyahu said Monday evening, according to a message circulated by his press office. “Our policy is clear — to respond immediately and with force. We harm whoever comes to harm us. That is how we have acted and how we will continue to act.”

No specific group claimed responsibility for the rocket fire on Monday, which came in three waves, at about 8:30 a.m., 10:15 a.m. and 12:30 p.m., according to a statement from the Israeli military. An antitank missile was also fired at Israeli troops patrolling the fence separating southern Gaza from Israel around 7:15 a.m., the statement said, and an explosive device was detonated near Israeli soldiers in the same area the night before.
