Humanitarian flights to the northern, rebel-held parts of Yemen have been grounded amid the blockade imposed by the coalition in response to a rebel missile attack near the Saudi capital, Riyadh, earlier this month. The missile was struck down but it marked the closest that a rebel projectile had come to the kingdom’s capital.

After widespread international criticism of its blockade, Saudi Arabia said last week it would reverse its closure of Yemen’s sea ports and airports — though not those in the hands of the Shiite rebels known as Houthis.

On Sunday night, a coalition airstrike in the northern Yemeni province of Jawf killed 10 civilians, including four women and two children, according to security officials and tribal sources in the area.

The airstrike targeted a house amid intense fighting in the area between forces loyal to Yemen’s coalition-backed and internationally recognized government, and the Iran-backed Houthis, the officials said, speaking on condition of anonymity because they were not authorized to talk to reporters.

There was no immediate word from the coalition on the airstrike or its intended target. The coalition, which began its war against the Houthis in 2015, claims the rebels often use civilians as human shields.

The civil war in Yemen, an impoverished Arab nation in the southwest of the Arabian Peninsula, has killed at least 10,000 civilians since it broke out in 2014.
