Israel has struck military tanks in southern Syria, where government forces and Bedouin tribes clash with Druze militias. Dozens of people have been killed in the fighting between local militias and clans in Syria's Sweida province. Government security forces that were sent to restore order on Monday also clashed with local armed groups. The Interior Ministry has said more than 30 people died and nearly 100 others have been injured in that fighting. U.N. Deputy Special Envoy for Syria Najat Rochdi has expressed "deep concern" over the violence in the country struggling for stability after a 13-year civil war.
