Officials in Pakistan have begun counting votes after polling ended in a general election marred by militant attacks and suspension of mobile phone services, with authorities saying that at least nine people had been killed nationwide.
The vote was held as the country struggles to recover from an economic crisis while it deals with rising militant violence in a deeply polarised political environment.
TV channels are expected to make projections of first results a few hours after voting closed at 5pm (12pm Irish time) and a clear picture is likely to emerge early tomorrow as counting continues through the night.
The national assembly has 265 seats and polling in one seat was postponed due to the death of a candidate.
A party needs 133 seats for a simple majority but many analysts believe the vote may not produce a clear winner.
Thousands of troops were deployed on the streets and at polling stations across the country and borders with Iran and Afghanistan were temporarily closed to ensure peaceful polling.
Despite the heightened security, nine people, including two children, were killed in bomb blasts, grenade attacks and shootings.
At least 26 people died in two explosions near electoral candidates' offices in the southwestern province of Balochistan yesterday. The Islamic State group later claimed responsibility for those attacks.
Today's victims included five police killed in a bomb blast and firing on a patrol in the Kulachi area of Dera Ismail Khan district in the northwest, authorities said.
Two children died in an explosion outside a women's polling station in Balochistan.
"Despite a few isolated incidents, the overall situation remained under control, demonstrating the effectiveness of our security measures," caretaker Interior Minister Gohar Ejaz said in a statement.
Mobile phone services suspended for security reasons are being partially resumed, the Interior Ministry said.
In spite of the security concerns and bitter cold, people lined up at polling stations hours before voting was due to start.
"The country is at stake, why should I come late?" said 86-year-old Mumtaz, a woman a decade older than Pakistan itself as she queued up in Islamabad.
Caretaker Prime Minister Anwaar ul Haq Kakar said there had been high voter turnout in "a clear indication of public commitment to shaping the future of our country".
The move to suspend mobile networks was criticised by opposition party leaders, with the Pakistan Peoples Party's Bilawal Bhutto Zardari, the 35-year-old son of assassinated former premier Benazir Bhutto, calling for its "immediate restoration".
Amnesty International called it "a blunt attack on the rights to freedom of expression and peaceful assembly".
Chief Election Commissioner Sikandar Sultan Raja said the decision on mobile networks was made by "law and order agencies" following yesterday's violence.
Jailed ex-prime minister Imran Khan's Pakistan Tehreek-e-Insaf (PTI) party, in a post on social media, called on people to remove passwords from their personal Wifi accounts "so anyone in the vicinity" could have internet access.
Former prime minister Nawaz Sharif, considered by many analysts to be the front-runner, dismissed talk of an unclear result.
"Don't talk about a coalition government. It is very important for a government to get a clear majority ... It should not be relying on others," he told reporters after casting his vote in the eastern city of Lahore.
The main contests are expected to be between candidates backed by Khan, whose party won the last national election, and the Pakistan Muslim League of Sharif, who analysts say is being backed by the military.
The military has dominated the nuclear-armed country either directly or indirectly in its 76 years of independence but for several years it has maintained it does not interfere in politics.
If the election does not result in a clear majority for anyone, as analysts are predicting, tackling multiple challenges will be tricky - foremost a new bailout programme being sought from the International Monetary Fund (IMF) after the current arrangement expires next month.
