Swedish climate activist Greta Thunberg was forced to temporarily leave the climate march in Madrid, Friday, December 6, due to a "safety issue," she said, caused by a large number of media and supporters who tried to get as close as possible to her. Despite trying to make her way to the march for over an hour, with a cordon of activists and security protecting her from crowds of fans and media trying to get a glimpse of her, she opted to leave the march temporarily and join it at the end, where she was set to address climate demonstrators. TV footage showed the 16-year-old being followed by dozens of photographers and camera operators, sometimes pushing into the cordon protecting her. (Reuters)
