Pakistan has been hit by violence on the day of its general elections - with at least 31 dead in the worst attack.
A man blew himself up outside a polling station in Quetta, in an attack claimed by the Islamic State group, BBC reported.
Preliminary, unofficial results suggest ex-cricket star Imran Khan's PTI party is in the lead as votes are counted.
However, the rival party of former PM Nawaz Sharif, PML-N, has rejected the results amid allegations of vote rigging.
