As the agency emphasizes, the visit took place against the backdrop of growing concerns about Afghanistan's ability to independently fight terrorism after the withdrawal of US troops.

In addition, a former Afghan security official familiar with the country's counterterrorism program told the agency that two of the six units trained and operated by the CIA to track the militants have already been transferred to Kabul's control.

The CIA did not comment on reports about the agency's director's work schedule.

On April 15, US Secretary of State Anthony Blinken arrived in Kabul to discuss with the Afghan authorities the "peace process" and the withdrawal of the American military from the republic.
