The Pakistan president's plane appeared to be fired on as it took off from a military airfield. Pervez Musharraf was on his way to visit flood victims in the south-western town of Turbat. Officials have denied the attack, but a Reuters photographer saw two large guns mounted on a roof of a house in an area close to the airport. This is the third attempt on Musharraf's life since he came into power in a military coup in 1999. It comes at a time of heightened tensions in Pakistan as security forces continue to lay siege to a mosque in Islamabad where a radical cleric and hundreds of students have been holed-up since Tuesday (July 02). Meanwhile, a suicide bomber threw himself at an army jeep killing six Pakistani soldiers in the volatile north-western region. It was the third attack against the army in as many days.
