Syrian state media reported late Tuesday an Israeli aerial attack near the Syrian capital of Damascus and in the central province of Homs, prompting a response from national air defenses.
The Syrian state news agency SANA said the Israeli attacks came from airspace over neighboring Lebanon. Loud explosions were heard in Damascus.
The target of the reported Israeli attacks were not immediately clear.
Israel has launched hundreds of strikes against Iran-linked military targets in Syria over the years but rarely acknowledges or discusses such operations.
Israel views Iranian entrenchment on its northern frontier as a red line, and it has repeatedly struck Iran-linked facilities and weapons convoys destined for Hezbollah.
The reported attacks are the first after a fragile truce ended last month's conflict between Israel and Hamas militants in the Gaza Strip.
