The Huthi rebels' health ministry said early Monday that new US air strikes on the Yemeni capital Sanaa killed at least 12 people and wounded 30.
The Huthi-run Saba news agency cited the ministry as saying the dead and injured had come from overnight strikes "by the American enemy" on a market and a residential zone in Sanaa's Farwa district.
Other raids were reported late Sunday in the central province of Marib, Hodeida in the west and the Huthi bastion of Saada in the north, Saba said.
The US military has been carrying out almost daily attacks for the past month, saying it was targeting the "Iran-backed Huthi terrorists" to stop attacks on international shipping in the Gulf.
One attack Thursday on the Ras Issa oil port killed some 80 people and injured 150, according to the Huthis.
UN Secretary General Antonio Guterres said Saturday that he was "gravely concerned" by the US strikes. But he also called on the Huthis to stop missile attacks on Israel and Gulf shipping.
The Huthis said they started missile attacks in solidarity with Hamas as it fights Israeli forces in Gaza. US raids started in January 2024 but have been stepped up since President Donald Trump took office this year.
On Sunday, at least two people were killed in overnight US strikes in and around Yemen's capital Sanaa, media controlled by the Huthi rebels reported Sunday, in the latest such air raid.
The Iran-backed group's Al-Masirah channel, citing the rebels' health ministry, reported two deaths and 11 injured in the "US aggression on Sanaa, the capital, and the governorate".
The TV channel earlier said one person was killed in an air strike on the governorate's Bani Matar area, where a deadly US raid was reported a week ago.
Beyond Sanaa, the Huthis said Sunday that air strikes also hit Yemen's Marib and Amran provinces.
Earlier this week, the rebel group said that US strikes on the fuel port of Ras Issa killed at least 80 people and wounded 150 in the deadliest attack of Washington's 15-month campaign against the Huthis.
The US military has hammered the Yemeni rebels with near-daily air strikes for the past month in a bid to stamp out their attacks on shipping in the Red Sea and Gulf of Aden.
Claiming solidarity with Palestinians, the rebels began attacking the key maritime route and Israeli territory after the Gaza war began in October 2023.
The US strikes began in January 2024 but have multiplied under President Donald Trump, starting with an offensive that killed 53 people on March 15.
Huthi attacks on the Red Sea shipping route, which normally carries about 12 percent of global trade, have forced many companies into costly detours around the tip of southern Africa.
