Five Taliban detainees were released to Qatar in a swap for Sgt. Bowe Bergdahl.

A U.S. official confirmed to Fox News that the former Guantanamo prisoner has been intercepted making telephone calls to the Taliban.

The development comes amid rising concerns over former Guantanamo detainees returning to the battlefield, and over the nature of the Bergdahl-Taliban trade itself last year, which was negotiated with the involvement of the Qatari government.

Despite the apparent outreach by one of the traded prisoners, all five of the so-called “Taliban 5” are still accounted for in Qatar, a senior U.S. defense official told Fox News.

"There are no indications that they are a risk right now,” another defense official said.

“I’m shocked, shocked to discover that one of the Taliban terrorists from Guantanamo is back in the business,” Krauthammer quipped. “Of course they’re back in the business […] I’m surprised it took them what? Six months or so?”

Krauthammer said that the idea that Qatar would prevent this activity is preposterous and said the U.S. must be honest about the consequences of its actions.
