BERN (Reuters) - Banner-waving climate activists rallied outside the Swiss parliament on Friday in support of a Global Climate Strike that youth movement Fridays for Future had called for ahead of the UN climate summit COP26.

       Protesters in Bern included young children and elderly people with banners reading "climate grandparents" and the words "oil, gas, coal" crossed out.

       Swiss media said 1,000-2,000 people took part in the protests. Similar gatherings took place in other cities including Basel and Biel.

       Fridays for Future had called for a global climate strike ahead of the Oct. 31-Nov. 12 COP26 conference in Glasgow to draw world leaders' attention to the need "to cut emissions drastically by divesting from fossil fuels", the movement said on its website.

       Swedish climate activist Greta Thunberg, who started Fridays for Future three years ago, told Reuters in an interview this month the conference would succeed only if world leaders admitted their actions were not living up to their words.
