Dozens were killed during clashes between Yemeni tribal fighters and Houthi rebels near the oil-producing Asailan area in the southern governorate of Shabwa, Al Arabiya News Channel reported citing local sources. Fighting erupted when tribal fighters attacked a Houthi-held area near Asailan. Almost thirty were killed among the Houthis and their loyalists during confrontations which also killed eight members of the tribes, a security source told Al Arabiya. The area was held by members of the Houthi militia and loyalists to former president Ali Abdullah Saleh. These developments come as a Saudi-led military campaign in Yemen enters its fifth day. Saudi Arabia, along with nine other states, has conducted a series of airstrikes targeting areas held by the Houthis.
