ISLAMABAD - Pakistani police charged with batons and fired tear gas and rubber bullets at thousands of protesters marching toward the prime minister's official residence and the adjacent parliament building in Islamabad on Saturday, blanketing the route with clouds of white smoke and scattering demonstrators. Nearly 125 people were injured in the clashes between police and demonstrators demanding the resignation of Prime Minister Nawaz Sharif.
Scores of protesters, mainly women carrying hammers and iron rods, broke down a fence outside the parliament building, enabling hundreds of people to enter the lawns and parking area, according to an Associated Press photographer at the scene and Pakistani television reports.
Islamabad police chief Khalid Khattak said the protesters were armed with big hammers, wire cutters and axes, and even had a crane.
Defense Minister Khwaja Mohammad Asif said police later managed to clear most of the protesters from the parliament building's parking area and lawns.
"Now only women and children are there, and they can take shelter there as long as they want."
Nearly 125 people -- including women, children and police officers -- were admitted to two government hospitals in the Pakistani capital, medics and police said. The injured had wounds from tear gas shells, batons and rubber bullets, said Dr. Tanvir Malik and another doctor who identified herself only as Ms. Abida.
The protest leaders, cricket-legend-turned politician Imran Khan and anti-government cleric Tahirul Qadri, had called on supporters staging a sit-in for days outside the parliament building to march on the prime minister's residence and the legislative chamber. About 20,000 police in riot gear were deployed to block the procession.
In speeches, Khan and Qadri called for protesters to remain peaceful and urged security forces to restrain from using force. Protests demanding Sharif's resignation were also taking place in Lahore, Karachi and other Pakistani cities, according to TV reports.
Khan described the police action against the crowd as illegal.
"Now we will show this government, we will call for countrywide agitation and we will jam the whole of Pakistan," Khan said.
Sharif's spokesman Asif Kirmani said the government had to use force after protesters tried to attack the center of state power in the capital. It was not clear whether Sharif was at the residence on Saturday.
"A state can't be left at the mercy of some thousand people," Kirmani said in an interview with Geo News TV.
Asma Jehangir, a human rights activist and political commentator, urged the government to take necessary measures to protect women and children in the protest, but criticized protest leaders for claiming that the demonstration would remain peaceful.
"It is like if you say 'a peaceful robbery'" she said.
Khan and Qadri, a dual Pakistani-Canadian citizen with a wide following, allege that Sharif won the 2013 election due to massive voter fraud and should step down. They also have demanded reforms in Pakistan's electoral system to prevent voter fraud.
Backed by parliament and many political parties, Sharif has said he will not step down. Government negotiators have tried to convince Qadri and Khan to end their protest.
The protests began with a march from the eastern city of Lahore on the country's Independence Day, Aug. 14, that reached Islamabad a day later. Khan and Qadri had called for millions of protesters to join but crowds have not been more than tens of thousands. The protesters' presence and heightened security measures have affected life and badly harmed business in the capital.
The protesters initially camped at another thoroughfare, but moved outside the parliament on Aug. 19. Until Saturday, the rallies had remained festive, with families picnicking and men and women dancing to drums and national songs.
Riot police initially showed restraint during Saturday's march but when the crowd started removing shipping containers used as barricades, they fired salvos of tear gas canisters that forced the crowds back. TV footage showed protesters, including women and children, scattering in retreat. Some fell to the ground and many protesters, including several children, were shown in TV reports being treated for the effects of tear gas.
Police refused to give any estimate about the size of the crowd that had been headed toward the prime minister's residence.
"They fired tear gas shells at us," said Ahsanullah Fakhri, 28, who was bleeding from his leg as he exited an ambulance with other injured protesters. "I think they are also firing some bullets, I think rubber bullets," he added.
Interior Minister Nisar Ali Khan visited the scene of the protests to boost police morale.
"A group wanted to capture the prime minister's house and other buildings. We are under oath, and the police as well, to protect the state assets," he told reporters at the scene.
