Obama heads off into Arctic wilds with Bear Grylls
Barack Obama has become the first serving US president to trek into the Alaskan wilderness - where he posted a selfie with Bear Grylls.
The Donaghadee-born adventurer is filming a special edition of Running Wild With Bear Grylls exploring the impact climate change is having on the Arctic.
Mr Obama teamed up with the TV presenter for a crash course in survival techniques. A beaming Mr Obama joked on the White House Instagram account: "Glad this is the only Bear I met in the park - Bo."
