ISLAMABAD (Reuters) - Fears of violence kept manyPakistanis away from the polls on Monday with 80,000 troopsbacking up police to watch over a vote that could choose aparliament set on driving President Pervez Musharraf fromoffice.
The election was originally scheduled for January 8 but theassassination of former prime minister Benazir Bhutto after arally in Rawalpindi on December 27 forced a delay.
Polls opened at 8 a.m. (3 a.m. British tmie) and will closeat 5 p.m. (12 p.m. British time). Results are expected to startemerging by midnight and trends should be clear on Tuesdaymorning.
The death of Bhutto, the most progressive, Western-friendlypolitician in a Muslim nation rife with anti-Americansentiment, raised concern about stability in the nuclear-armedstate.
Well over 450 people have died in militant-related violencethis year.
Voting was slow with witnesses across the country reportinga trickle of voters. The Election Commission said turnout wasabout 15 percent three hours after polls opened. Monday is aholiday with banks and schools closed and traffic thin onroads.
A woman voter, Azra Khalid Shaikh, heading into a pollingstation in the city of Karachi, said she wanted to set thecountry back on a path to democracy.
"This is the starting point," she said.
Former army chief Musharraf's popularity plunged over thepast year because of his manoeuvres to hold on to power whichincluded purging the judiciary and six weeks of emergency rule.
Many Pakistanis also blame the government for risingprices, shortages of staples and all too frequent power cuts.
Security concerns affect large parts of Pakistan, whereMusharraf has ruled since seizing power in a 1999 coup, and asuicide attack on Bhutto party supporters killed 47 people in anorthwestern town on Saturday.
"You see suicide bombings everywhere and you can see theempty streets on polling day. It's all because of fear," saidcivil servant Mohammad Ijaz, voting in the city of Lahore wherethree people were killed in shootings late on Sunday.
Four people were killed in election-related violence inPunjab province after polls opened, police said.
Militants set off bombs at four polling stations in thenorthwest, three in the Swat Valley, before polls opened but noone was hurt.
Army helicopters later attacked suspected militant hideoutsin Swat, residents said.
COALITION SEEN
The other worry is rigging, which could prompt oppositionparties to reject the result and call for street protests,raising concern over how the powerful army would react.
The country of 160 million people has alternated betweencivilian and army rule throughout its 60-year history.
Otherwise, a sympathy vote is expected to help Bhutto'sPakistan People's Party (PPP) become the largest party in the342-seat National Assembly.
"Bhutto's mission is still alive, we will work for that,"said Manzoor Ali, 60, voting with his wife and daughter inBhutto's native district of Larkana in Sindh province.
Most analysts doubt the PPP can win a majority. Who itchooses for coalition partners will be vital to Musharraf.
Bhutto's widower Asif Ali Zardari, co-chairman of the PPP,issued a conciliatory call for unity on the eve of the vote.
He did not comment to reporters as he voted in Sindh. Theleader of the other main opposition party, former primeminister Nawaz Sharif, made a victory sign as he voted inLahore.
An alliance between the PPP and Sharif is what Musharrafdreads as Sharif is intent on bringing him down, perhapsthrough impeachment. Analysts say Musharraf wants a coalitionbetween the PPP and the Pakistan Muslim League that backs him.
Western allies, who want a stable Pakistan to focus onfighting militancy, hope for a smooth vote, as do investors ina stock market that rose 40 percent last year but has shedabout 3 percent since Bhutto's death.
International credit ratings agency Standard & Poor's saidon Monday that Pakistan was among several countries facingrisks on account of political instability.
Nearly 81 million people are registered to vote. Severalhundred foreigners, including a team of U.S. senators, andthousands of Pakistanis have fanned out to monitor the vote butare not allowed to do exit polls.
"We don't presume to suggest that by hitting severalpolling stations to know whether the poll is fair. All we cando is get a sense," U.S. Senator Joseph Biden told reporters inLahore.
Biden has said the United States should cut military aid toPakistan unless the election is credible but said unconditionaleconomic assistance should be increased if it is fair.
