The Saudi-led coalition in Yemen shelled the Houthi's Air Defense Brigade 630 near the country's fourth-largest city of al-Hudaydah, sources told Al Arabiya News Channel channel on Tuesday. The coalition has also destroyed a missiles depot belonging to the militias of the deposed President Ali Abdullah Saleh, west of the capital, Sanaa. Saudi-led air forces also targeted Saleh's hometown of Sanhan, south east of Sanaa. Meanwhile, military sources said that the Popular Resistance forces that are allied to legitimate President Abdrabbu Mansour Hadi seized control of the strategic Al-Anad air base in the country's southern province of Lahej. In Aden, Houthi rebels and Saleh loyalists have reportedly resumed the shelling of residential neighborhoods, killing around 200 people, mainly civilians. Saudi Arabia, which supports current President Hadi, has been leading an airstrikes' campaign since March 26 against the Iranian-backed rebels. Violence has sharply escalated in the poor country following the beginning of the campaign against Houthis. The United Nations backs Hadi as Yemen's legitimate leader in the face of a Houthi coup that has plunged the Arab state deeper into chaos. The Houthis and forces loyal to Saleh seized the capital Sanaa in February, and last month advanced on the port city of Aden, Hadi's stronghold, forcing him into exile.
