"Congratulations to Nawaz Sharif. I hope he is now able to live up to his commitment to restart his peace process interrupted in 1999," Omar tweeted as early poll trends showed Sharif set for a third term as Pakistan's Prime Minister.
"I suppose we'll have to wait for a post election scenario to emerge in our country before any meaningful engagement can begin #IndoPak," Omar posted on micro blogging site Twitter.
As per Pakistan TV projections, no single party would win a simple majority of 172 seats in the 342-member National Assembly.
"Given the bloody election Pakistan has seen I hope they now realise that there can be no good terrorists & bad terrorists, all terror is bad," Omar posted.
During election campaigning, Sharif in various interviews had stressed on the importance of resolving the Kashmir issue peacefully and suggested that back channel negotiations should be reactivated.
