More than 100 emergency officials are combing the site of the industrial building explosion in the Saudi capital of Riyadh in a search for victims.
Survivor Kushnoo Akhtara, 55, who was at work in the building, which housed the operations of a heavy machinery distributor, when the blast occurred said "lots of people" were left under rubble.
I was inside the building when the blast came. Then boom, the building collapsed. Furniture, chairs and cabinets blasted into the room I was in. My brother is still inside under the rubble. There are lots of people in there.
