I've just heard from a Nepalese friend who is a guide out there, he says emotions are running high because four expert Sherpa climbers have sadly lost their lives this season. He also says the mountain is very busy this season.
As Shewie says, we may not hear the full story but I hope this adds some context and balance; whether it's connected to the scuffle or not I think most people who are familiar with Nepalese culture realise that there is a lot more to this incident than has been reported in the popular media.
Certainly I'm not being deterred from planning my next trip out there, which will hopefully be Mera Peak led by a team of Nepalese men and women I know (and respect and trust)
