Yemeni officials said an airstrike by the Saudi-led coalition hit a market in northern Yemen, killing at least 10 civilians, including children. They said the strike took place in the Saada province, a stronghold of Iran-aligned rebels known as Houthis. The coalition has been battling the rebels on behalf of an internationally recognized government since 2015 in a war that has killed tens of thousands of people. There was no immediate comment from the coalition.
