Houthi media in Yemen reported Wednesday at least 17 strikes in Saada and Amran, blaming the United States for the attacks.
The group's Ansarollah website said US warplanes carried out "aggressive air raids... causing material damage to citizens' property", but gave no details of casualties.
Washington on March 15 announced a military offensive against the Iranian-backed Houthis, promising to use overwhelming force until the group stopped firing on vessels in the key shipping routes of the Red Sea and Gulf of Aden.
That day saw a wave of US air strikes that officials said killed senior Houthi leaders, and which the militants' health ministry said killed 53 people.
Since then, Houthi-held parts of Yemen have witnessed near-daily attacks that the group has blamed on the United States, with the group announcing the targeting of US military ships and Israel.
The Houthis began targeting shipping vessels after the start of the Gaza war, claiming solidarity with Palestinians, but paused their campaign when a ceasefire took effect in Gaza in January.
Earlier this month, they threatened to renew attacks in the vital maritime trade route over Israel's aid blockade on the Palestinian territory, triggering the first US strikes on Yemen since President Donald Trump took office in January.
Last week, Trump threatened to annihilate the Houthis and warned Tehran against continuing to aid the group.
