An air strike killed dozens of people at a camp for displaced people in northwest Yemen on Monday, aid workers said, as Arab warplanes bombard rebels around the country. The International Organization for Migration said 45 internally displaced people had been killed and 65 wounded at the Al-Mazrak camp in Hajja province. IOM spokesman Joel Millman told AFP that the organisation had 75 staff on hand assisting the victims. "It was an air strike," said MSF's Middle East programme manager Pablo Marco.
