At least 22 people were killed on Wednesday in tank and mortar shelling by rebel forces on residential areas in Yemen's second city Aden, a medic and a local official said.
"Twenty-two dead and more than 70 wounded have been transferred to several hospitals in Aden," a medical official told AFP, adding that most of the casualties were civilians.
A local official confirmed that Shiite Huthi rebels and troops loyal to ex-president Ali Abdullah Saleh "randomly shelled... civilian homes" in Mualla and Crater districts of Aden.
The same sources said that clashes between local militias, known as "popular committees" and Huthis left several fighters dead on Wednesday but could not immediately provide a toll.
A military source said that 11 people were killed in Aden overnight in clashes between rebels and forces loyal to fugitive President Abedrabbo Mansour Hadi.
