BEIRUT (REUTERS) - An Israeli drone crashed in southern Lebanon overnight between Friday (March 30) and Saturday, the Israeli military and Hizbollah's Al-Manar TV reported.

"An unmanned Israeli spy plane crashes between the villages of Beit Yahoun and Baraachit," Al-Manar reported.

A statement from the Israeli military said the drone had crashed because of a technical malfunction.

"The incident is currently being reviewed. There is no risk of leaked information," the statement said.

Israel and Lebanon's Hizbollah last fought a war in 2006. Israeli and US officials say Iran is helping the group build factories to manufacture precision-guided missiles or refit its longer-range missiles with precision guidance systems.

The heavily armed Hizbollah joined the Syrian civil war in support of Syrian President Bashar al-Assad in 2012, and has played a critical part in helping his government defeat Sunni rebels backed by the United States and its regional allies - Saudi Arabia, Qatar and Turkey.

Hizbollah has spearheaded a coalition of Teheran-backed Shi'ite militias that have deployed to Syria from Iraq, Afghanistan and Pakistan. Iran's expanding power in Syria has caused deep alarm in neighbouring Israel.

Israel has mounted numerous air strikes in Syria against what it has described as Hizbollah and Iranian targets.

Sheikh Naim Qassem, the deputy leader of the Iran-backed Shi'ite group, told Reuters in an interview on March 15 that Hizbollah does not expect Israel to launch a war for now in Lebanon, but that it is prepared for one.
