A drone launched by Hezbollah passed through Israel’s air-defense systems and hit an Israeli military base near Binyamina in central Israel.

Israel has one of the world’s best defenses against missiles and rockets, but struggles to detect slower-moving unmanned aircraft, experts said.

A drone struck central Israel on Sunday, wounding 61 people, a few of them seriously. It was one of the bloodiest attacks in Israel in a year of war.

A drone strike by Hezbollah on a military base in the north of Israel killed four soldiers and wounded dozens of other people, the Israeli military said Sunday.

Israel’s military said Thursday it killed a Hezbollah commander in southern Lebanon, while also announcing a new round of evacuation orders in the Bekaa Valley. The Israel Defense Forces identified the commander killed as Hussein Awada and said he was responsible for firing projectiles across the border into Israel.

Israeli airstrikes pounded areas across Lebanon, killing at least 27 people during the past 24 hours, officials said Wednesday, including more than a dozen in a southern town where Israeli bombardments in previous conflicts are seared into local memory.
