Egyptian media reports say supporters of the Muslim Brotherhood, to which deposed President Mohamed Morsi belonged, are the culprits behind the act of violence. They say at least one person has been arrested in connection with the aggression.

On Friday, 12 people were killed and at least 200 injured in the Egyptian city of Alexandria during clashes between thousands of opponents and supporters of the ousted president.

The fierce clashes between rival factions erupted after Friday prayers in the Mediterranean city over the ouster of Morsi in a military coup.

Dozens have lost their lives and over a thousand have been injured in the latest spate of violence in Egypt.
