This comes as National Security Council on Sunday said US-Taliban Taliban deal did not lead to an end to war and bloodshed.
Rahmatullah Andar NSC spokesman tweeted that there were no necessary consultations conducted with the Afghan government during the US-Taliban deal.
The accord to end the long-term war in war-weary Afghanistan was not effective.
Andar said the agreement was not effective and could not stop bloodshed and war and did not put an end to the “dark days for Afghans”.
Security forces have set the protection of Afghanistan their first priority and it is their responsibility to look at matters like peace, war, and other related aspects.
