ISLAMABAD: Pakistan Tehreek-iInsaf (PTI) chief Imran Khan in a tweet on Friday taunted Nawaz Sharif over his `friendship` with Indian Prime Minister Narendra Modi and accused the two leaders of creating the law and order situation in the country or tension at the border to manipulate the situation in favour of the PML-N.

`Beginning to wonder why whenever Nawaz Sharif is in trouble, there is increasing tension along Pakistan`s borders and a rise in terrorist acts? Isit a mere coincidence?` the PTI chief tweeted.

He made the comment at 2.30pm on Friday after condemning the attack on JUI-F leader Akram Durrani`s cavalcade in Bannu which left four people dead.

Mr Khan`s tweet was based on a slogan frequently raised by PTI workers and supporters at its public meetings: `Modi Ka Jo Yaar Hai, Ghaddar Hai, Ghaddar Hai (friend of Modi is a traitor)`.

Mr Khan later also tweeted about the Mastung suicide bombing: `Another condemnable terrorist attack on a political gathering this time in Mastung. Saddened to learn of Nawabzada Siraj Raisani`s shahadat in this targeted attack as well as the shahadat of other innocent citizens.
