Re: Breaking News: Blast rocks Peshawar

An explosion at a Shia mosque in the Pakistani city of Peshawar has left at least four people dead, officials say.

The cause of the explosion, which came as the Shia Muslim community prepared to mark the Ashura festival, was not immediately clear.

"There was a powerful explosion in a congested area of Peshawar and we have sent teams to the scene," a security official told AFP news agency.

Local television reported six people had been killed in the blast.
