Violence between pro-government fighters and those seeking an independent south has flared since Wednesday ADEN: At least six civilians were killed and 12 others wounded Friday during clashes in Yemen’s second city Aden, a security source said, as violence flares between pro-government fighters and those seeking an independent south. The fighting erupted on Wednesday and has continued unabated between the two sides, who are in effect backers of the Aden-based internationally recognized government of President Abedrabbo Mansour Hadi. One faction however is known as the Security Belt, a force dominated by fighters who seek independence for southern Yemen. On Friday, fierce clashes broke out between the two sides during which a mortar round crashed into a house killing six people, four of whom were from the same family, a security source said. Twelve other people were wounded in the fighting, the source said. Doctors Without Borders (MSF) tweeted Friday that it had treated 75 people in a hospital run by the charity “since yesterday (Thursday) night” including seven who were in a critical condition. “Most of the patients we admitted are civilians and were injured by shrapnel during shelling on their houses or stray bullets,” MSF said.
