The death toll from fresh U.S. airstrikes on a crowded market in Yemen's capital Sanaa on Sunday evening has risen to 12, with at least 30 others wounded, Houthi-controlled health authorities said in a statement.

According to Houthi-run al-Masirah TV, the airstrikes targeted the Farwah market in the Shu'ub neighborhood, one of the busiest markets in Sanaa. Rescue operations are ongoing, with teams searching for survivors and victims beneath the rubble.

The strikes were part of a broader wave of U.S. airstrikes that hit multiple locations in and around Sanaa on Sunday, the Houthi media outlet added.

The incident came days after the deadly U.S. airstrikes on the Ras Isa fuel port in western Yemen late Thursday night that killed 80 people, wounded 170 others, and caused widespread damage to fuel storage infrastructure, leading to fuel spills into the Red Sea, according to local Houthi health officials.

Tensions between the Houthi group and the U.S. military have escalated since Washington resumed airstrikes on Houthi targets in Yemen on March 15 to deter the group from attacking Israel and U.S. warships in the Red Sea.

The Houthis, which control much of northern Yemen, said their attacks aim to press U.S.-backed Israel to stop the offensive against the Gaza Strip and allow the entry of humanitarian aid into the Palestinian enclave.
