The Iran-backed Lebanese group Hezbollah carried out an operation on Monday against the Israeli army in the disputed Shebaa Farms area at the Lebanese-Israeli border, Lebanese sources familiar with the operation said.

The operation was made in response to an Israeli attack in Syria in which a Hezbollah fighter was killed last week, one of the sources said.

Israel’s army ordered residents along its northern border to stay inside following a “security incident” in the occupied Golan Heights.

“Following the security incident in the Mount Dov area... residents are asked to stay in their houses. Any kind of activity in open areas is forbidden,” an army statement said.

The restrictions apply to “the residents of the area along the Israeli side of the Blue Line” that separates Lebanon from Israel, the army added.
