Yemen Crisis: Inside Sanaa as fighting continues
The United Nations has called on all sides in the Yemen conflict to abide by international law.
The UN's humanitarian coordinator for Yemen, Johannes van der Klaauw, said it was unacceptable that civilians and aid workers had come under attack.
The Saudi-led coalition says its aircraft have only targeted military camps, air bases, weapons depots and rebel headquarters, but civilian areas have often been hit.
The UN estimates that more than 560 people have been killed, many of them civilians, in air strikes, fighting and bomb attacks in Yemen since 19 March.
A local journalist captured footage after strikes in the capital Sanaa.
