"Human Rights Watch is accusing the Saudi Arabia-led coalition of dropping banned cluster bombs manufactured and supplied by the U.S. on civilian areas in Yemen. Cluster bombs contain dozens or even hundreds of smaller munitions designed to fan out over a wide area, often the size of a football field. They are banned under a 2008 treaty for the high civilian toll they can cause. The treaty was adopted by 116 countries — although not by Saudi Arabia, Yemen or the United States. According to Human Rights Watch, the U.S.-supplied cluster bombs have landed near rebel-held villages in northern Yemen, putting residents in danger. On Monday, the State Department said it is "looking into" the report’s allegations, adding it takes "all accounts of civilian deaths in the ongoing hostilities in Yemen very seriously."
