Karachi: Former military dictator Pervez Musharraf on Sunday ended nearly four years in self-exile defying threats of arrest and assassination by Taliban, saying that he returned home to “save” Pakistan and would face all “challenges” that lay ahead. 69-year-old Musharraf along with a delegation of around 150 people, including supporters from his All Pakistan Muslim League and journalists, landed at Jinnah International airport here from Dubai.
