A suicide bomber killed at least 29 people near a polling centre as Pakistanis voted on Wednesday in a knife-edge general election pitting cricket hero Imran Khan against the party of jailed ex-Prime Minister Nawaz Sharif.
The Islamic State militant group claimed responsibility for the attack that hospital officials said killed 29 people and wounded 35 in the western city of Quetta. Security sources said the bomber drove his motorcycle into a police vehicle.
About 106 million people are registered to vote in polls due to close at 6 p.m (1300 GMT). The likely winner should be known by around 2 a.m. on Thursday.
Sharifโs party on Wednesday afternoon called for voting to be extended by an hour, saying people were still lining up and could be turned away without casting ballots. Local TV channels said election officials denied the request.
About 371,000 soldiers have been stationed at polling stations across the country, nearly five times the number deployed at the last election in 2013.
Earlier this month, a suicide bomber killed 149 people at an election rally in the town of Mastung in Baluchistan province. That attack was also claimed by Islamic State militants.
According to the latest opinion polls, neither Khan nor Sharif are likely to win a clear majority in the election.
Khan has emerged as a slight favourite in national opinion polls, but the divisive race is likely to come down to Punjab, the countryโs most populous province, where Sharifโs party has clung to its lead in recent surveys.
The election has been plagued by allegations the powerful armed forces have been trying to tilt the race in Khanโs favour after falling out with the outgoing ruling party of Sharif, who was jailed on corruption charges this month.
โImran Khan is the only โhope to change destiny of our country. We are here to support him in his fight against corruption,โ said Tufail Aziz, 31, after casting his ballot in the north-western city of Peshawar.
ANTI-CORRUPTION CRUSADER
Whichever party wins, it will face a mounting and urgent in-tray, from a brewing economic crisis to worsening relations with on-off ally the United States to deepening cross-country water shortages.
An anti-corruption crusader, Khan has promised an โIslamic welfare stateโ and cast his populist campaign as a battle to topple a predatory political elite hindering development in the impoverished mostly-Muslim nation of 208 million people, where the illiteracy rate hovers above 40 percent.
โThis is the most important election in Pakistanโs history,โ Khan, 65, said after casting his vote in the capital Islamabad.
โI ask everyone today โ be a citizen, cherish this country, worry about this country, use your vote.โ
Khan has staunchly denied allegations by Sharifโs Pakistan Muslim League-Nawaz (PML-N) party that he is getting help from the military, which has ruled Pakistan for about half of its history and still sets key security and foreign policy in the nuclear-armed nation. The army has also dismissed allegations of meddling in the election.
STRUGGLE TO WIN
Khanโs Pakistan Tehreek-e-Insaf (PTI) party has inched ahead of PML-N in recent national polls, but even if it gets the most votes, it will likely struggle to win a majority of the 272 elected seats in the National Assembly, raising the prospect of weeks of haggling to form a messy coalition government.
Such a delay could further imperil Pakistanโs economy, with a looming currency crisis expected to force the new government to turn to the International Monetary Fund for Pakistanโs second bailout since 2013. PTI has not ruled out seeking succour from China, Islamabadโs closest ally.
Sharifโs PML-N has sought to turn the vote into a referendum on Pakistanโs democracy, and has said it was campaigning to protect the โsanctity of the voteโ.
The Pakistan Peoples Party (PPP), which has been overtaken by Khanโs PTI as the main challenger to PML-N but is widely seen as the likely kingmaker, has also alleged intimidation by spy agencies.
Sharifโs PML-N has been touting its delivery of mega infrastructure projects, especially roads and power stations that helped hugely reduce electricity blackouts, as proof the country is on the path to prosperity.
โIf we get the opportunity, we will change the destiny of Pakistan,โ said Shehbaz Sharif, brother of Nawaz and the PML-N president, as he cast his vote in Lahore. โWe will bring an end to unemployment, eradicate poverty and promote educationโ.
PML-Nโs campaign was reinvigorated by the return to Pakistan of Nawaz Sharif, 68, who was earlier this month convicted and sentenced in absentia to 10 years in prison over the purchase of upscale London apartments using offshore companies in the mid 1990s. He has denied any wrongdoing.
The election will be only the second civilian transfer of power in Pakistanโs history.
Khan has in recent years shed his playboy image and adopted a more pious and conservative persona. He has vowed to create 10 million jobs if he comes to power and promised to build โworld classโ schools and hospitals.
