The U.S. military carried out two airstrikes on Yemen's northern Saada province Tuesday night, Houthi-run al-Masirah TV reported.

The strikes targeted the Sahar district in central Saada, the report said, without providing further details. There were no immediate reports of casualties. The U.S. military has not commented.

Saada is the main stronghold of the Iran-aligned Houthi movement, which has controlled northern Yemen, including the capital Sanaa, since the civil war erupted in late 2014.

The airstrikes are part of an ongoing U.S. campaign against Houthi-controlled areas in Yemen, launched in mid-March.

The Houthis have vowed to continue targeting Israeli sites and ships in solidarity with Palestinians in Gaza and to retaliate against "American aggression."
