Pakistan has been hit by violence on the day of its general elections - with at least 31 dead in the worst attack.
According to unofficial results, the PTI party is currently leading in 109 national assembly seats, while PML-N is ahead in about 67 seats, with only 26% of the votes have been counted so far, according to local media
The campaign has been overshadowed by concerns of fraud and violence, and the Human Rights Commission of Pakistan says there have been "blatant" attempts to manipulate the polls.
In addition to a suicide attack in Quetta, in Balochistan province, one person died from a grenade attack in Khuzdar, and another died in a shooting between political rivals in Swabi, Khyber Pakhtunkhwa province.
