PESHAWAR: Pakistan Tehrik-i-Insaf (PTI) and political parties in the coalition decided, on Sunday, to postpone a sit-in scheduled to take place on Nov 20, against Nato supply routes because of the sectarian clashes in Rawalpindi, DawnNews reported.

The announcement was made during a press conference in Peshawar.

PTI Chief Imran Khan had vowed to block Nato supplies from crossing through Khyber Pakhtunkhwa in response to the US drone strike that killed Pakistani Taliban chief Hakimullah Mehsud on November 1 and "sabotaged" peace talks.

Khyber Pakhtunkhwa is one of the two key routes Nato supplies move in and out of Afghanistan and is seen as crucial as US-led allied forces prepare to draw down from the war-torn country in 2014.

Opposition parties in Pakistan have accused the US of using the drone strike to stymie the peace process before proper talks had even started.

Khan, whose party leads the provincial government in Khyber Pakhtunkhwa, had said: “Even if we lose our provincial government, we will not let Nato supplies pass through as long as drone strikes do not stop.”
