A Syrian surface-to-air missile exploded in southern Israel on Thursday, the Israeli military said, in an incident that triggered warning sirens in an area near the secretive Dimona nuclear reactor.
There were no immediate reports of any injuries or damage in Israel.
The military said that in response to the launch, it attacked several missile batteries in Syria, including the one that fired the projectile that struck southern Israel.
Syria’s state news agency said Syrian air defences intercepted the Israeli attack that targeted areas in the Damascus suburbs.
“Air defences intercepted the rockets and downed most of them,” the agency said.

Israeli Army Radio said the Syrian missile had been fired at Israeli aircraft during an earlier strike and had overflown its target and reached the Dimona area.
A Reuters reporter about 90 km (56 miles) north of Dimona heard the sound of an explosion minutes before the military tweeted that sirens had gone off in the region.
The errant Syrian missile was an SA-5, one of several fired at Israeli air force planes, according to an Israeli military spokesman. It did not hit the reactor, he added.
Israeli media have said for weeks that air defences around the Dimona reactor and the Red Sea port Eilat were being beefed up in anticipation of a possible long-range missile or drone attack by Iranian-backed forces – perhaps from as far away as Yemen.
Tensions are high between Israel and Iran over Tehran’s nuclear programme and a recent surge in sabotage attacks, some of which the arch-foes have blamed on each other.
Early on Thursday, the Saudi-led coalition battling Yemen’s Houthis intercepted a drone attack by the Iran-aligned movement on the southern Saudi city of Khamis Mushait, state media reported.
