巴基斯坦议会选举投票站外爆炸致70多人死伤

At least 31 people were killed and 40 wounded in an explosion outside a polling station in southwest Pakistan Wednesday, just hours after millions of voters began casting their ballots in parliamentary elections.

A senior police official told VOA that a suicide bomber on a motorcycle attacked a crowd outside a polling station in Quetta. The victims included voters, police personnel and political party activists.

The radical Islamic State has claimed responsibility for Wednesday's blast. Quetta is the capital of Baluchistan province, where a powerful suicide bombing at an election rally earlier this month killed 151 people, including a provincial assembly candidate. The radical group Islamic State also took credit for plotting the carnage.

The election has narrowed to a contest between ex-Prime Minister Nawaz Sharif’s former ruling Pakistan Muslim League-Nawaz ((PML-N)) and the Pakistan Tehreek-e-Insaf ((PTI)), led by former cricket star Imran Khan, who has pledged to eliminate corruption and create a "Islamic welfare state."

The PML-N has accused the military of helping Khan and the PTI to win the election, a charge Khan and the military have strongly denied. The military has ruled the Muslim-majority nation of more than 200 million people for nearly half of the country's 70-year-history.

Neither the PML-N nor the PTI are expected to win a majority in the 342-seat National Assembly, lower house of parliament, meaning whoever wins will have to enter into negotiations with smaller parties to form a coalition government.

Voters elect 272 members to the parliament while the other 70 are reserved for women and minorities and are given to various political parties based on their percentage of winning seats.

Wednesday's election is just Pakistan's third peaceful transition of power.
