Another two senior members of the Afghan Taliban are reported to have been captured in Pakistan.
Mullah Abdul Salam and Mullah Mir Mohammad are reported to have been captured about two weeks ago.
The New York Times says they were in the town of Akora Khattak in the North West Frontier Province.
If confirmed, the arrests would be a further blow to the Taliban following the capture of Mullah Abdul Ghani Baradar by US and Pakistani intelligence agents in Karachi on 8 February.
Mullah Abdul Salam is said to be the Taliban's chief commander for northern Afghanistan.
The capture of Mullah Baradar was confirmed by the White House on Wednesday.
