The United Nations peacekeeping force UNIFIL said on Thursday it was working with Lebanese authorities to extinguish wildfires that have spread for several kilometers in south Lebanon after being started by gunfire along the Lebanese-Israeli border. Lebanese civil defense fire brigades have been working on extinguishing the fire, UNIFIL spokesperson Andrea Tenenti told Reuters, adding that strong winds and a heat-wave, along with minefields, increased the risk of the fires spreading.
