By Daniel Wallis and Deisy Buitrago CARACAS (Reuters) – Venezuelan authorities freed 25 student protesters on Friday pending trial and said that 74 others arrested after this week’s deadly political turmoil would be processed within hours. In a more affluent part of eastern Caracas, police used teargas and water cannons to clear a square of about 1,000 protesters, some of whom lit fires and threw stones at the security forces. The protesters also briefly blocked a major highway nearby, denouncing President Nicolas Maduro over a litany of grievances including the repression of demonstrations since three people were shot dead this week following an opposition-led march. Speaking at a televised event in the city center alongside top officials from the ruling Socialist Party and pro-government sports stars and entertainers, Maduro said he would not let the protesters cause chaos by closing important arteries.
