A Saudi-led aerial bombing campaign has entered its second day in Yemen. The Saudi-led airstrikes are intended to thwart the advance of Shiite Houthi rebels after they seized control of the capital Sana’a last year and deposed President Abdu Rabbu Mansour Hadi last month. On Thursday, Hadi left his refuge in Aden for Saudi Arabia. At least 39 civilians have reportedly been killed so far in the airstrikes. Amnesty International reports the dead include at least six children under the age of 10.
