The prisoner swap is part of a deal between the Taliban and the United States, which was signed in the Qatari capital, Doha, on February 29, and under which the militant group agreed to halt attacks on international forces in return for the US military’s phased withdrawal from Afghanistan.
The Afghan government, which was not a signatory to the US-Taliban accord, was required to release up to 5,000 Taliban prisoners. The militants, for their part, were obliged to free 1,000 government captives.
While the Afghan government has been releasing Taliban prisoners, it has balked at releasing some of the members tied to deadly attacks.
A Reuters report on Thursday cited European diplomats as saying anonymously that European countries backed that refusal.
“There are some dangerous Taliban fighters named in the list, and releasing them is literally crossing a red line,” a senior European diplomat told Reuters. “Some NATO members find it extremely uncomfortable to support the release of Taliban prisoners who were behind large-scale suicide attacks on minority groups and on expats.”
Kabul has already released around 3,000 prisoners under the agreement. The Taliban has also freed hundreds of captives.
According to the sources, some prisoners accused of involvement in large-scale attacks — such as the 2017 truck bombing near Germany’s Embassy in Kabul, which killed more than 150 people — are among those that the militant group wants released.
The Taliban has threatened to scrap the deal with the US if the members that it wants are not released.
