An industrial building in Saudi capital Riyadh was almost entirely destroyed by a large explosion on Thursday, Nov 1, Reuters reported.

The building was almost levelled by the blast, with one corner left standing, the witness said. Nearby vehicles were on fire and at least five fire engines were arriving at the scene.

Al Arabiya television said that the blast was caused by a fuel truck exploding at a petrol station.

According to latest reports, 10 were killed.
