Kabul: A spokesperson for the Afghan Taliban termed the decree signed by President Ashraf Ghani to facilitate the release of some Taliban prisoners in Afghan jails as "conditional", saying the release order went against the agreement signed between the militant group and the US last month, Dawn reported.

"We never agreed to any conditional release of the prisoners. If someone claims this, it will be against the peace accord that we signed on February 29," Suhail Shaheen spokesman for the Taliban said.

Sediq Seddiqi, spokesperson for the Afghan president, in a tweet said that Ghani had signed the decree that would facilitate the release of some Taliban prisoners in accordance with an accepted framework for the start of negotiations between the Taliban and the Afghan government.

At least 1,000 Taliban prisoners are expected to be released this week, official sources said earlier, paving the way for opening direct talks between the Afghan government and the Taliban.

Seddiqi also hinted that Kabul would consider releasing 5,000 prisoners if the Taliban refrained from attacks on Afghan forces.
