Security officials in Yemen say at least 20 people have been killed or wounded in an airstrike by the Saudi-led coalition targeting a building used by police in the capital, Sanaa.
The officials, who are loyal to anti-government Shiite rebels known as the Houthis, say several people are believed to be still trapped under the debris.
The building was partially used as a gathering point for security forces.
The airstrike happened shortly before midnight on Sunday, according to the officials, who had no further details. Reporters were barred from approaching the facility, they said, speaking Monday on condition of anonymity because they were not authorized to speak to the media.
