An air strike in the Yemeni capital that killed at least 14 civilians, including eight members of one family, was due to a technical mistake, according to the Saudi-led coalition battling rebels.
At least three families lived in the three-storey building bombed in the Fag Attan area of Sanna.
Friday's bombing was accidental and unintentional, said coalition spokesman Colonel Turki al-Maliki who expressed "sincere sympathy".
Col al-Maliki said the planned target was a legitimate military objective belonging to the Houthi rebels, who control the capital.
The incident came just days after at least 41 people died when aircraft bombed a small hotel in the town of Arhab, north of Sanaa.
