Fighting broke out over Aden International Airport on 19 March after Hadi dismissed a general in Aden , Abdul-Hafez al-Saqqaf , whom he suspected of being loyal to Ali Abdullah Saleh , widely believed to be an ally of the Houthis . The next day , a quadruple suicide bombing ripped through two mosques in Sanaʽa while hundreds of Houthis were praying there . The Revolutionary Committee declared a " state of general mobilisation " in response to the events and launched a military offensive directed at Hadi 's holdouts , whom the Houthis accused of being in league with al-Qaeda
