Israeli soldiers killed two guerrillas before dawn Monday in Israel's self-proclaimed security zone in southern Lebanon, a military spokesman said.

No Israeli troops were hurt in the clash, the spokesman said.Troops opened fire after encountering the guerrillas during a routine patrol in the central sector of the 6-to-10-mile-wide security zone near the village Barachit, the army said.

The guerrillas were heavily armed with submachine guns, hand grenades and rocket-propelled grenades, the army said. Israel army radio said they were probably planning to attack an Israeli target within the security belt.
