International Workers’ Day”, is the celebration that international labour movement and left-wing movements. ”1923” is the first year when it has ever celebrated officially in Turkey. It is accepted as ‘’holiday’’ including in Turkey. This year celebration is at ”Taksim”.  Taksim is going to be closed to traffic, also many people attend this celebration every year but unfortunately bad situations have happened past years by malicious people even though there were huge security precautions. So, be careful.. :)
