Reports from Yemen say some 60 people have been killed at a prison complex in air strikes by a Saudi-led coalition.
Security and medical officials said the strikes hit the Al-Zaydiya security headquarters in the western port of Hudaydah on October 29.
The city is under the control of Houthi rebels, who have been battling the government since 2014.
Rebels and inmates were said to be among the dead.
The Houthi’s media put the death toll at 43.
Hours earlier, warplanes bombed houses in the western city of Taiz, killing at least 15 people, residents reported.
The Saudi-led coalition, which backs Yemen’s exiled President Abu-Rabbu Mansur Hadi, has been criticized for the number of civilians killed in its air strikes.
