The deputy political chief of Taliban Mullah Abdul Ghani Baradar met with Zalmay Khalilzad, the U.S. envoy for Afghan peace in Qatari capital of Doha.

Suhail Shaheen, a spokesperson for the political office of Taliban in Doha, said Mullah Baradar, leading a delegation of the Taliban leaders, met with Khalilzad in Doha.

According to Shaheen, the two sides held talks on the need to expedite the release of prisoners, launch of intra-Afghan talks and full implementation of the peace deal between Taliban and the United States.

This comes as the Afghan government recently released hundreds of Taliban prisoners in a bid to help the peace process.

On the other hands, the Taliban group is accused of stepping up attacks against as the officials warn that the continued violence could endanger the peace process.

Khalilzad issued a statement on Twitter last week, warning that the increase in number and lethality of Taliban attacks could endanger gains.

He said civilians still suffer from IEDs, targeted assassinations, and other consequences of the ongoing war, emphasizing that “To protect them all sides must act now to end the violence.”
