Former president Pervez Musharraf has returned to Pakistan after nearly four years of self-imposed exile to contest the upcoming general election.
He decided to return despite the possibility of arrest and recent death threats from the Taliban.
Mr Musharraf hopes to regain influence so that his party can win seats in the vote, which is predicted to take place in May.
He told his supporters outside Karachi's airport: "People said I would not come. Where are those people now? People were trying to scare me. I only fear Allah, no one else."
