"The insurgents will launch coordinated car bomb attacks in Islamabad and Lahore. The master mind of this attack, Mohammad Yasin, is an expert in car bombings," a Pakistani Interior Ministry official told Pakistan's The News.
The claims were rejected by the Afghan National Directorate of Security deputy spokesman Shafiqullah Taheri.
"We strongly reject this. Unfortunately, Pakistan's military officials are providing false information to their political leaders," Taheri said.
Meanwhile, the former Afghan Deputy Minister of Interior, General Abdul Hadi Khaled, believes that NDS is facing its own insurgent challenges within Afghanistan and does not have time to plan for any attacks in other countries.
This comes as 8 suicide attackers target one of the biggest air bases in Islamabad earlier this month.
