Athens (AFP) - Greek police used tear gas Thursday during clashes with hundreds of Muslim immigrants protesting in Athens over reports that an officer had desecrated the Holy Quran. Around 1,500 demonstrators marched through the working class district of Kypseli towards the Omonia Square in the city centre, where there were scuffles with officers and tear gas was fired, said police. Demonstrators said that on Wednesday, as police officers stopped four Syrian immigrants to check their papers, one of the officers had desecrated the Holy Quran. After word spread of the alleged incident, the local Muslim immigrant community, mainly from Afghanistan and Pakistan, organised Thursdays protest. Police have so far not commented on Wednesdays alleged incident.
