Israel said its aircraft struck Hezbollah targets in Lebanon on Saturday and that one of its soldiers was hit by an anti-tank missile, in cross-border fighting that the Iran-backed group said killed six of its fighters.

The Israeli army said it fired back.
Hezbollah, which claimed attacks on Israeli military positions throughout Saturday, later said five other members were killed. Israel said its soldiers struck a cell attempting to launch anti-tank missiles toward the area of Shlomi, an Israeli town some 70 km (44 miles) from Margaliot.
