The leader of Lebanon's militant Hezbollah group says if Israel attacks Iran's nuclear facilities, Iran will not order his group to retaliate.

Sheik Hassan Nasrallah says in case of such an attack, his leadership would meet and decide what to do. He spoke to supporters by video link.

The Iran-backed Hezbollah has been in conflict with Israel since 1982, when Israel invaded Lebanon. Israel pulled out in 2000.

In 2006, Hezbollah and Israel fought a 34-day war the killed 1,200 people in Lebanon and 160 in Israel. Hezbollah fired nearly 4,000 rockets at Israel.

Many fear if Israel attacks Iran, Hezbollah will unleash a barrage of rockets at Israel in retaliation.

Israel considers Iran to be its most dangerous enemy and has vowed to prevent it from acquiring nuclear weapons.
