Hezbollah says calls not to intervene in war 'will have no effect'

STORY: "We follow the moves of the enemy, and we are fully ready. When the time comes for any action, we will carry it out," he told supporters gathered in the southern Beirut suburb for a rally.

The group has already clashed with Israel across the Lebanese border multiple times in the past week in the deadliest confrontations since they fought a month-long war in 2006.

The cross-border rocket fire and shelling followed the assault by Palestinian faction Hamas against Israeli towns and Israel's retaliatory bombardment of the Gaza Strip.

But sources say Hezbollah has designed its moves so far to be limited in scope, preventing a big spillover into Lebanon while keeping Israeli forces occupied.
