A Hezbollah drone attack on an army base in central Israel killed four soldiers and severely wounded seven others Sunday, the military said, in the deadliest strike by the militant group since Israel launched its ground invasion of Lebanon nearly two weeks ago.

Hezbollah said the drone attack was in retaliation for two Israeli strikes in Beirut on Thursday that killed 22 people.

More than 60 people have been injured in a drone attack in Israel, according to first responders.
