At least 25 people were killed and many others wounded when a Saudi-led air strike targeted a police headquarters overnight in Yemen's capital Sanaa, authorities said on Monday.
A hospital official said 25 policemen were confirmed dead, while the others, including civilians, were receiving treatment.
"About 30 people, including policemen and residents who live in houses near the police facility, have been transferred to hospitals," a security official at the scene told Xinhua.
"More than a dozen of policemen were still under the rubble and rescue teams have been trying to save possible survivors," he said.
The Saudi-led coalition started its air strikes on Houthis rebels and their allied forces in March 2015, amid efforts to restore President Abd-Rabbu Mansour Hadi's rule and force the Houthis to retreat from cities they have seized since September 2014.
