A day after the Supreme Court quashed several legal challenges to Musharraf's bid for a new five-year term, the Election Commission gave its nod of approval, said Kanwar Dilshad, a top commission official.
More legal maneuvers are expected from the opposition, but the general appears to have cleared his biggest hurdles to contesting the Oct. 6 vote by federal and provincial lawmakers.
"Yes, President Musharraf's nomination papers have been approved," Dilshad said. "He's eligible to run."
The commission approved only six of 43 candidates, including Musharraf's two main challengers: Wajihuddin Ahmed, a retired judge nominated by lawyers, and Makhdoom Amin Fahim, vice chairman of ex-Prime Minister Benazir Bhutto's Pakistan People's Party, the official said. A full list was to be released later Saturday.
Musharraf was nominated by Prime Minister Shaukat Aziz and 16 other allies for another five-year term. Shortly after they arrived at the commission to respond to objections filed by Musharraf's opponents, about 200 lawyers
- who earlier burned copies of the court ruling - tried to approach from the nearby Supreme Court building.
Scenes of chaos ensued on barricaded Constitution Avenue. Police fired tear gas shells and beat the protesters, with at least one officer using a tree branch. An Associated Press reporter saw two lawyers with head injuries.
Television footage also showed police arresting some female supporters from Bhutto's party and shoving them into a waiting van. At least two opposition legislators also were dragged away.
Running clashes continued for more than two hours. Several journalists were beaten by police, with ARY news channel correspondent Asma Shera saying they were deliberately targeted. An AP reporter was slightly injured when a government vehicle hit him outside the Election Commission, where journalists were protesting the police tactics.
Deputy Information Minister Tariq Azim was pummeled by protesters when he arrived. He was rushed into a car by his aides and driven away.
Lawyers also rallied in Lahore and Karachi, where police arrested some and beat others.
It was the first in Islamabad protest since a crackdown on the opposition began a week ago. The government defended the arrests of hundreds of opposition activists nationwide as necessary to maintain law and order in the face of promised street protests.
But the chief justice ordered their immediate release after security forces sealed off the capital Thursday, when Musharraf's nomination papers were filed.
Despite dwindling popularity and increasingly bitter opposition, Musharraf, a close U.S. ally, appears set to win the Oct. 6 vote by federal and provincial legislators. The general's main challenger is Wajihuddin Ahmed, a retired judge nominated by lawyers.
Ahmed's supporters held out hope that the commission might disqualify Musharraf, although analysts said that was highly unlikely.
