Two people were killed and seven others, including two Lebanese army soldiers, were wounded in an overnight shootout in east Lebanon's city of Baalbek, security sources said.

They said the shooting was triggered by a "personal quarrel" in al-Ain near Baalbek in which Raifeh Saleh, 52, was killed and three other people were wounded, including the town's mayor, Youssef Jaafar, 47.

The sources said a military vehicle which was transporting the wounded to hospital came under fire near the town of Nabi Othman on the road leading to Baalbek, prompting Lebanese troops to return fire.

A man was killed and four people, including two soldiers, were wounded in the exchange of fire, according to the sources.
