Deadly Explosions Rock Pakistan's Counterterrorism Office in Swat Valley

Two explosions at a counter-terrorism office in Swat Valley, Pakistan, have killed at least 12 people, most of whom are police officers. The cause of the explosions is believed to be an electrical fault igniting ammunition in the centre. The Pakistani Taliban has not claimed responsibility for the attack. The Swat Valley was controlled by Islamist militants before they were forced out in 2009, and has been prone to insurgency.
