This is the best summary I could come up with:

Hezbollah and Israel fought a brutal month-long war in 2006 and have traded sporadic fire over the border since then while avoiding a major conflict.

The man was killed on Monday in Israeli shelling into southern Lebanon prompted by a cross-border raid claimed by the Palestinian Islamic Jihad group, which has been fighting alongside Hamas since it launched its surprise attack on Israel on Saturday.

Some residents of southern Lebanon said they were leaving homes along the border with Israel amid heavy shelling that had so far pounded the outskirts of towns and villages.

A series of incidents over the past months had already elevated the risk of escalation along the Lebanon-Israel border before the last days of fighting in Israel and Gaza.

Israel’s Army Radio gave the location as being near Adamit, across from the Lebanese border towns of Aalma El Chaeb and Zahajra.

A spokesperson for the U.N.'s peacekeeping mission said its head Major General Lazaro was “in contact with the involved parties, urging them to exercise maximum restraint.”
