The release of prisoners on both sides is the precondition for intra-Afghan talks. France and Australia objected to Kabul freeing several Taliban prisoners who are suspected of attacking citizens of these two countries.
A source said last week that the government delegation would head to the site of the peace talks in Doha with the remaining prisoners.
"The process of releasing of prisoners of the Islamic Emirate has not been finalized yet, the release of some prisoners is still on pending and work is underway. Once the releasing process of prisoners complete, our negotiating team is ready to begin inter-Afghan negotiations," Wardak told Sputnik on Tuesday.
Afghan presidential spokesman Sediq Sediqqi said on Monday there were no more obstacles for the consultations.
Sources said on Sunday that the Afghan government's delegation had completed its preparations for the talks and would leave for Qatar later on the same day.
