En jihadist-gruppe åpnet søndag ild mot den libanesiske hæren utenfor Saida, og hæren besvarte ilden. Volden har dermed spredt seg fra nord til sør.
Det er gruppa Jund al-Sham som fyrte av en RPG mot en kontrollpost og såret fem.
Near the southern city of Sidon, suspected members of the militant Islamic group Jund al-Sham fired a rocket-propelled-grenade at a Lebanese army checkpoint outside a camp Sunday, wounding at least five people, security officials said on customary condition of anonymity.
The attack prompted a shootout between the troops and militants, causing people to flee into homes and mosques for safety. It was not clear if the attack was related to the conflict in the north, but several hardline Islamic groups have called on Muslims to support Fatah Islam.
