It's been a week of firsts on Everest.
BBC NEWS:
Wedding on top of Mount Everest A Nepalese couple have exchanged wedding vows on top of Mount Everest, the first people ever to marry there.
Pem Dorjee and Moni Mulepati briefly took off their oxygen masks and put on plastic garlands, while the groom symbolically applied red powder on the bride's forehead.
The couple stayed on the peak for a mere 10 minutes which gave enough time for the ceremony and for friends to take photos.
The bride told BBC's Newshour programme other climbers were "very surprised, they are really shocked."
The groom said other couples had wanted to do the same in the past, but none had managed because they could not get up on top of the peak together.
One Nepalese paper joked that this was a marriage which, if not made in heaven, was solemnised closest to it.
It's been a busy week at Mount Everest. On Monday, 45 climbers scaled the 8,850-metre (29,035-feet) peak - including Pem Dorjee and Moni Mulepati the couple who got married.
