A Saudi-led airstrike on Yemen's Taiz killed at least 55 people and left tens injured, Houthi-controlled news agency Saba said on Saturday. A coalition of Arab states, led by Saudi Arabia, has been bombarding Iran-allied Houthi forces in Yemen since late March in a bid to reinstate President Abd-Rabbu Mansour Hadi, who has fled to Riyadh. The Saba agency quoted a local source in Taiz as saying that the bombing targeted the Mokha area inhabited mostly by engineers and workers of a power station and some displaced families.
