Taliban claims Afghan bomb attack, demands prisoner release
As part of the pact, the Taliban agreed to open power-sharing talks with the US-backed government.
But a senior government official said there was still no agreement on starting the talks.
"The government will start the process of release in the coming few days and will complete the release whether the Taliban agree or not," he said.
A diplomatic source said US special envoy Zalmay Khalilzad, who has overseen the negotiations with the Taliban, has been pressing Taliban leaders to compromise on the prisoner issue and there were hopes the hurdle would be overcome.
"Momentum is such that it would not be possible for any side to back out," the source said.
