Rocket warning sirens went off on Thursday in Israel’s Golan Heights, but the IDF quickly said it was a false alarm.

“It appears to have been a false alarm,” the military said in a statement. “The IDF’s Iron Dome aerial defense system was activated. The circumstances are being looked into.”

Local residents said they heard a blast at the time of the sirens, but they were not sure what had caused it.

Tensions are high along the frontier. On May 10, Israel said Iranian forces in Syria fired rockets at it, but they were intercepted by its Iron Dome defense system.

Israel then launched its most intensive air strikes into Syria since the start of the Syrian civil war. It said it targeted Iran’s military infrastructure in Syria.
