A well-known Norwegian mountaineer has denied accusations that her team climbed over an injured guide during a bid to break a world record.

Speaking to the BBC's The World Tonight programme, Ms Harila said members of her team tried to help Mr Hassan but it was "not possible" to get him back down the narrow route, which was crowded with other climbers.

Ms Harila said she did not see exactly what took place, but the next thing she knew, Mr Hassan "was hanging upside down" on a rope between two ice anchors, with his harness "all the way down around his knees.

Her team tried for an hour-and-a-half to fasten a rope to the guide and give him oxygen and hot water, she recounted, until "an avalanche went off around the corner".
