Cairo: The Israeli military said in the early hours of Saturday that sirens sounded in a number of areas in central Israel following launches that crossed from Lebanon into Israeli territory.
The military said shortly afterwards that three projectiles crossed from Lebanon, some of which it said were intercepted.
"A fallen projectile was most likely identified in the area," the army added, noting that the details were under examination.
The Islamic Resistance in Iraq said later in a statement it had targeted a "vital target" north of Israel with drones. It was not immediately clear if the group's action was related to the sirens.
The development comes as Israel's escalation in Lebanon continues and fighting between the Israeli forces and the Lebanese Hezbollah group rages on.
