BEIRUT (Reuters)—Lebanon's armed group Hezbollah launched a series of drone and rocket attacks into northern Israel on Tuesday but warned that its much-anticipated retaliation for Israel's killing of a top commander last week was yet to come.

Hezbollah said it launched a swarm of attack drones at two military sites near Acre in northern Israel, and also attacked an Israeli military vehicle in another location.

The Israeli military said a number of hostile drones were identified crossing from Lebanon and one was intercepted.

Israeli medical officials said seven people were evacuated to a hospital, to the south of the coastal city of Nahariya, one in critical condition.
