Spectator taking selfie causes another crash at Tour de France, prompting calls for caution

A spectator trying to take a selfie on stage 15 caused a crash involving around two dozen riders.
The crash was triggered when the spectator's outstretched arm clipped American cyclist Sepp Kuss.
Overall leader Jonas Vingegaard and several teams appealed to fans to be more careful and give riders space.
The incident comes after similar crashes caused by spectators in previous editions of the Tour.
Vingegaard retains a slim 10-second lead over Tadej Pogacar heading into the rest day.
