JERUSALEM (JTA) — The Israel Defense Forces attacked a Syrian army artillery target in response to a mortar from Syria that landed in Israeli territory on the Golan Heights.

The mortar shell that exploded Sunday evening in Israeli territory was errant rebel fire from Syria’s civil war. No warning sirens were triggered and no injuries were reported.

“The IDF holds the Syrian government accountable for this clear breach of Israeli sovereignty, and will continue to act in order to safeguard Israel,” the army said in a statement.

Several stray rockets and shells have landed in Israel since the start of the civil war in Syria more than five years ago. The IDF frequently retaliates by firing at the source of the shells.
