The Lebanese militant group captured an advanced Israeli anti-tank missile in the 2006 war, and its ally, Iran, reverse-engineered it, Israeli officials say.

For years, Israelis were told that in the next war with Hezbollah, the Lebanese militia would fire thousands of rockets and missiles a day, overwhelming their air defenses, causing blackouts, death and destruction.

These missiles have a range of up to 10 miles and they carry advanced guidance seekers to track and lock onto targets.

As U.S. diplomat Amos Hochstein visited the region to push for a ceasefire, Israel struck Beirut’s southern suburbs and the eastern Bekaa region, and a barrage of rockets fired from Lebanon killed a man in northern Israel.
