ADEN — Yemeni Houthi rebels are targeting civilian homes in Aden's port district of Mualla using army tanks, residents told Al Arabiya News Channel on Saturday night. The strikes killed many, including children, the residents said, adding that parts of the southern port city have been without water or electricity for two days, according to Reuters news agency. The Houthis bombarded residential areas, setting fire to several buildings and damaging others, witnesses said. Residents reported casualties and said dozens of families had fled their homes in the port city, the heart of which sits on an extinct volcano jutting out into the sea. “Snipers, who took position on the roofs of provincial government buildings, targeted passersby and members of the popular committees,” said Khalid Bashaea, a fighter loyal to the legitimate government of President Abdrabbu Mansour Hadi. Residents said life was becoming unbearable. “How long can people live without water or electricity?” said Mohammad Fara'a. Another resident, Hassan Abdallah, said people were using a long-disused well at one of the mosques to get water. Meanwhile, in the southern city of Dalea, Houthis have reportedly executed seven civilians the group was holding as captives. The Houthis and militias of the deposed leader Ali Abdullah Saleh seized power in the capital Sanaa in February and last month advanced on the port city of Aden. — Agencies
