A video of a group of Nepali climbers taking their last steps together to the K2 summit while singing Nepal's national anthem has gone viral. The climbers made history by becoming the first mountaineers to complete a winter attempt to summit K2. The group of sherpas stopped at a point 70 metres from the peak and waited for one another before finally taking their last steps. The group huddled together to take their final, historic steps. “Brother to brother, shoulder to shoulder, we walked together to the summit...", Nirmal Purja, a member of the group, tweeted the incredible video.
