Fresh blast in Riyadh

Reports from Saudi Arabia say there's been an explosion at a shopping mall in the capital, Riyadh, causing damage but no injuries.

The cause of the blast was not immediately clear.

One report said it seemed to emanate from a telephone booth.

The incident follows a series of bomb attacks late last year in which one Briton was killed and a number of others injured.
