An air strike on a Scud missile base in the Houthi-controlled Yemeni capital Sanaa triggered a big explosion that killed 25 people and wounded almost 400 on Monday, state news agency Saba said.
Saudi Arabia has led an alliance of Sunni Arab countries in air strikes against the Iran-allied Shi'ite Houthi group and army units loyal to ex-president Ali Abdullah Saleh.
"Twenty-five citizens were killed and more than 398 were wounded, mostly women and children, according to a preliminary figure after the Saudi aggression's bombing today," said the agency, which is run by the Houthis.
The number could not be immediately verified, but medical sources told Reuters at least 15 people had been killed and scores wounded.
The blast hit the base on Faj Attan mountain beside the Hadda district, home to the presidential palace and many embassies, blowing out the windows of homes for kilometers around and sending a tall mushroom cloud into the air.
