Pakistan’s President Pervez Musharraf narrowly escaped an assassination attempt Sunday. He was returning home near the capital Islamabad when a bomb went off seconds after his convoy drove over a bridge. No one was hurt in the blast. President Musharraf said he was certain he was the target. No group has said they carried out the attack and a high-level investigation has been launched. It is the second serious attempt on the Pakistani president’s life since he ordered a crackdown on Islamic militants nearly two years ago.
