DUBAI (AP) ― Former Pakistani President Pervez Musharraf ended more than four years in self-exile Sunday with a flight to his homeland, seeking a possible political comeback in defiance of judicial probes and death threats from Taliban militants.

The journey from exile in Dubai to the Pakistani port city of Karachi is intended as the first step in his goal of rebuilding his image after years on the political margins. Since the former general was forced from power,

Pakistan’s civilian leadership has struggled with a sinking economy, resilient Islamic extremist factions and tensions with Washington over drone strikes and the secret raid that killed Osama bin Laden.

Musharraf represents a polarizing force that could further complicate Pakistan’s attempt to hold parliamentary elections in May and stage its first transition from one civilian government to another.

He is viewed as an enemy by many Islamic militants and others for his decision to side with America in the response to the Sept. 11, 2001 terrorist attacks.

On Saturday, the Pakistan Taliban vowed to mobilize death squads to send Musharraf “to hell” if he returns.

His supporters, including elements of the military and members of Pakistan’s influential expatriate communities, consider him a strong leader whose voice ― even just in parliament ― could help stabilize the country.

Musharraf also faces legal charges, including some originating from the probe of the 2007 assassination of former Prime Minister Benazir Bhutto, who also spent time in self-imposed exile in Dubai before returning.

The flight from Dubai came after several failed promises to return in recent years. Musharraf announced in early March that he would lead his party, the All Pakistan Muslim League, in May elections.

Musharraf met briefly with reporters in Dubai before heading to the airport wearing a white shalwar kameez -- the traditional loose-fitting outfit in Pakistan -- and sandals from the country’s Peshawar region near the Afghan border.

Musharraf took power in a 1999 coup and was forced to step down in 2008 amid growing discontent over his rule. He has since lived in Dubai and London.

His decision to return was given a boost last week when a Pakistan court granted him pre-emptive bail -- essentially preventing his immediate arrest -- in three cases in which he’s implicated, including Bhutto’s death. He now has 10 days to appear in court. He has dismissed the various charges as baseless.

His return comes as Pakistan seeks for the first time to hand power from one elected government to another. The country, meanwhile, is struggling with rolling blackouts, rising inflation and widespread security problems.

On Saturday, the Pakistan Taliban released a video threatening to unleash suicide bombers and snipers against Musharraf if he comes back. One of the two people speaking in the video was Adnan Rashid, a former Pakistani air force officer convicted in an attack against Musharraf. The Taliban broke Rashid out of prison last year, along with nearly 400 other detainees.

“The mujahedeen of Islam have prepared a death squad to send Pervez Musharraf to hell,” said Rashid, who spoke in the video in front of a group of about 20 militants holding rifles. “We warn you to surrender yourself to us. Otherwise we will hit you from where you will never reckon.”

Musharraf had been expected to address supporters at a gathering Sunday in Karachi near the mausoleum of Pakistan’s founding father Mohammed Ali Jinnah. But police decided to cancel his permit because of a “very serious threat,” said Tahir Naveed, the deputy inspector general of Karachi police. He said Musharraf would be provided with an armored vehicle to protect him due to the threats. Banners and billboards welcoming Musharraf back to Pakistan lined the street from the airport where he is expected to land.
