Saudi Arabia-led coalition forces appear to have used cluster munition rockets in at least seven attacks in Yemen’s northwestern Hajja governorate, killing and wounding dozens of civilians. The attacks were carried out between late April and mid-July 2015.

“The loss of civilian life in Hajja shows why most countries have made a commitment never to use cluster munitions,” said Ole Solvang, senior emergencies researcher at Human Rights Watch. “These weapons not only kill or injure people at the time of attack, but the unexploded submunitions go on killing long afterward.”
