CAIRO — Yemen’s Houthi rebels said Saturday that the U.S. military launched a series of airstrikes on the capital, Sanaa, and the Houthi-held coastal city of Hodeida, less than two days after a U.S. strike wrecked a Red Sea port and killed more than 70 people.

The Houthis’ media office said 13 U.S. airstrikes hit an airport and a port in Hodeida, on the Red Sea. The office also reported U.S strikes in Sanaa.

There were no immediate reports of casualties.

The U.S. military’s Central Command, which oversees American military operations in the Middle East, said it continues to conduct strikes against the Houthis in Yemen.

Thursday’s strike hit the port of Ras Isa, also in Hodeida province, killing 74 and wounding 171 others, according to the Houthi-run health ministry. It was the deadliest strike in the United States’ ongoing bombing campaign on the Iranian-backed rebels, which has killed about 200 since March 16, according to the Houthis’ health ministry.
