Pakistan's former military ruler Pervez Musharraf, who is on trial for treason, narrowly escaped what police called an assassination attempt as a roadside bomb went off shortly before his convoy was due to pass by early yesterday.
The bomb was planted on Musharraf's route from an army hospital in Rawalpindi, where he has been staying since January, to his home on the outskirts of Islamabad.
It was the fourth apparent attempt on the former general's life, with the first three occurring while he was in office.
"Four kilograms of explosive device planted in a pipeline under a bridge exploded around 20 minutes before the former president was supposed to cross the spot," senior police official Liaqat Niazi said.
The blast occurred at the Faizabad interchange, on the boundary of the two cities, and destroyed a section of footpath.
Niazi said Musharraf was taken home via an alternative route.
Muhammad Naeem, a spokesman for the Islamabad police, confirmed the incident, saying a bomb disposal squad had cordoned off the area after the blast and searched for additional explosives. The blast ripped up a small section of the brick footpath. Police later removed the security cordon tape and traffic was passing freely.
"Nobody was injured in the blast," he said, adding Musharraf was the intended target. There have been no claims of responsibility for the blast so far.
Musharraf, who led Pakistan from 1999 to 2008, returned from self-imposed exile in March last year to fight in general elections, but was barred from taking part and has faced a barrage of legal cases including treason.
The Taliban had vowed to send a squad of suicide bombers to kill him, and security threats prevented Musharraf from appearing at all but two of his treason hearings.
Prior to hospital treatment for a heart condition, several bombs were discovered by officials near his villa.
Some commentators in the domestic media said those explosives may have been planted by insiders in order to exaggerate the threat to Musharraf's life and expedite his safe passage out of the country through a behind-the-scenes deal.
But a spokesman for the former general said yesterday that he was in "real danger".
"Musharraf's life is in real danger from the threat of extremist terrorist groups," Raza Anjum, a London-based aide said. "He is No 1 on the terrorists' hit list. We call upon the government of Pakistan to ensure that those who perpetuated this planned assassination attempt are brought to justice," he said.
On Monday, a special court indicted Musharraf for treason, in what was seen as a milestone for civilian authority in a country long dominated by the army.
The charges relate to Musharraf's 2007 imposition of emergency rule, which came as the Supreme Court was due to rule on the validity of his re-election as president.
Treason carries the maximum penalty of death, but some analysts were sceptical of whether the government would allow the trial to be seen through to its completion and risk a greater clash with the military.
Musharraf had also sought permission to leave the country to see his ailing mother in the United Arab Emirates, leading to renewed speculation that a deal, which would allow all sides to save face, was imminent.
But the government on Wednesday refused to end a travel ban preventing Musharraf from leaving the country.
"The interior ministry has sent a written reply to Musharraf refusing to lift travel bans as there are a number of cases against him," an official of the interior ministry said.
Musharraf was believed to be keen to return from hospital to his comfortable villa in the scenic Bani Gala suburb of Islamabad.
Ahmad Raza Kasuri, a member of his legal team, said Musharraf had discharged himself. "He left at his own request and was with his son Bilal," he said.
Pakistan's Nazwaz Sharif authorises release of at least 16 Taliban prisoners
Pakistan has freed at least sixteen Taliban prisoners with the approval of Prime Minister Nawaz Sharif in a move designed to invigorate a shaky peace process with the militant group. The Pakistani Taliban called a one-month ceasefire on March 1 but said this week it would not extend the truce because the government was not serious about meeting its demands, which include release of prisoners. The political agent of South Waziristan, the highest government official in the northwestern tribal region, confirmed the government had started releasing non-combatant prisoners to boost reconcilliation efforts.
All the released prisoners belonged to the Mehsud tribe, a major Pashtun tribe living in South Waziristan. Sharif personally authorised the releases, a source in his office said - an apparent sign he is giving in to pressure from the Pakistan Taliban and resisting those in the military arguing for tougher military action against militant strongholds.
