TBILISI, July 14 (Reuters) – Four television channels in Georgia went off the air on Wednesday in protest at the death of a cameraman who was beaten up during violence against LGBT activists, and demanded the prime minister’s resignation. Hundreds of people took to the streets of the former Soviet republic’s capital, Tbilisi, on Sunday to demand punishment for those responsible for Alexander Lashkarava’s death. He was found dead at his home by his mother after being hurt when groups opposed to a planned pride march ransacked an LBGT campaign office last week, his employers at TV Pirveli said. The march was called off. TV Pirveli was one of the four channels that went off the air and displayed the names of journalists injured on the day the campaign office was attacked.
