In Pakistan, at least 13 people killed and 50 injured by two explosions in a counter-terrorism ammunition depot yesterday. Provincial police Chief Akhtar Hayat said the explosions rocked the counter-terrorism office in northwestern Swat valley, which was previously long controlled by Islamist militants before they were flushed out in a military operation in 2009. A spokesman said in a statement issued later that ammunition caught fire, most probably due to an electric short-circuit. No evidence of an attack from outside has been established so far <br />
