Sanaa girls' school deserted after air strike

Waleed Noman of the UN's children's charity, Unicef, gives Orla Guerin a tour of a girls' school in Yemen's capital, Sanaa, that was deserted after a Saudi-led coalition air strike across the road.

Over the past year, the Houthi rebel movement and military units loyal to Yemen's former president have been battling a US-backed, Saudi-led coalition supporting the country's internationally-recognised government.

Almost 6,300 people, half of them civilians, have been killed in the fighting, according to the UN.
