Strikes killed more than 30-civilians in a mountainous northern Yemeni province Saturday, U.N. humanitarian-chief for the country said, calling the attack "shocking." The Yemeni-rebels, known as Houthis, accused the Saudi-led coalition of launching retaliatory airstrikes, after they shot down a warplane for coalition over the province of Jawf. Al-Maliki was quoted as saying the plane was providing air support for Yemeni-government-forces fighting the Houthis.
