Smart bombs were used to bomb Panjshir, former Samangan MP Zia Arianjad said as quoted by various media.

Taliban spokesperson Zabihullah Mujahid Monday declared victory of the insurgent group over the resistance forces in the northeastern province of Panjshir.

"Panjshir province, the last stronghold of the mercenary enemy, was completely conquered," he said in a tweet, after a night of intense fighting between the Taliban, aided reportedly by Pakistani special forces, in the holdout province.

Fahim Dashty, the spokesperson of Ahmad Massoud, who is leading the resistance force, was killed during a fight with the Taliban Sunday night.

The National Resistance Force has proposed the Taliban to withdraw from Panjshir and in return it will refrain from any military action, India Today reported.

Meanwhile, Pakistan ISI chief Lt Gen Faiz Hamid met with Taliban leader Abdul Ghani in Kabul Sunday.

As the United States has withdrawn its troops from the country after 20 years, insurgent group Taliban invaded Afghanistan almost completely on Aug 15 by storming into the capital city of Kabul.

Following the invasion, men, women rushed to the Kabul Airport in a desperate attempt to flee the country and take refuge in other parts of the country.
