At least 500 Houthi rebel group fighters were killed since the start of the Saudi-led Arab coalition operation against the group in Yemen, a security source told Saudi Press Agency (WAS) Saturday. Earlier Saturday, the coalition spokesperson, Ahmed Assiri announced in a press conference that the coalition conducted 1200 airstrikes against Houthi rebel group in Yemen since the beginning of "Storm of Resolve" operations. Assiri added that the coalition launches 80 airstrikes per-day, pointing out that the airstrikes have become more focused on Houthis' camps. Yemen has been living in a state of chaos since the Houthi insurgency launched an uprising against the Yemeni government, taking over large parts of the country.
