Three British men are being held in Taliban custody in Afghanistan, UK non-profit group the Presidium Network said on Saturday.

The group said on Twitter it had been "working closely with two of the families." 

According to Sky News, so-called "danger tourist" Miles Routledge was among those detained. 

The other two men are charity medic Kevin Cornwell and another unidentified UK national who manages a hotel in Kabul, the report said.

"The government is in negotiations and working hard to ensure people's safety is upheld," Interior Minister Suella Braverman told Sky News.

No contact

Scott Richards of the Presidium Network told Sky News: "We believe they are in good health and being well treated."

"We have no reason to believe they've been subject to any negative treatment such as torture and we're told that they are as good as can be expected in such circumstances."

The Foreign, Commonwealth and Development Office (FCDO) said it was trying to make contact with the captives, although Richards later said that "no meaningful contact" with the men, two of which are believed to have been in captivity since January.

"We are working hard to secure consular contact with British nationals detained in Afghanistan and we are supporting families," a spokesperson for the FCDO told Reuters in a statement without confirming the details of the British nationals.

Routledge, 23, has gained fame, and attracted controversy, by traveling to dangerous countries and posting about it online.
