Rocket alarm sirens heard in Israel's Eshkol Regional Council, near the Gaza border, on Sunday were later confirmed to be a false alarm.
The sirens come two days after Israel's "Arrow" missile defense system shot down an anti-air projectile near Jerusalem that had been fired by Syrian government forces. That incident was part of a larger clash in Syria with Israeli Air Force jets, the most serious such occurrence since the beginning of Syria's civil war six years ago.
A day later, on Saturday, a rocket fired from Gaza struck an open area in southern Israel. No one was injured in the attack. The IDF retaliated with aircraft and artillery fire, targeting two Hamas positions in northern Gaza.
This is a developing story.
