Flash floods caused by heavy rains have killed 15 people and left nine missing in Yemen's Taiz Governorate, with extensive damage reported, state-run Saba news agency said on Sunday.

The agency said the floods, triggered by torrential rains early Friday, struck host communities and camps for internally displaced persons in western and northwestern Taiz.

A preliminary government report confirmed the deaths included women and children, while nine others remain missing in Mocha, a port city of the governorate.

Initial estimates indicated nearly 5,900 families were affected, with homes partially or completely damaged. Yemen's meteorological authorities warned residents to avoid valleys and low-lying areas during and after rainfall.
