"Street terrorism..." Turkey President Erdogan as massive protest continue for 4th day in Istanbul. Thousands Rally Across Turkey Over Mayor Ekrem Imamoglu's Arrest Thousands of people gathered outside Istanbul's city hall for a second consecutive night on Thursday to rally against the arrest of the city's mayor, a prominent contender against President Recep Tayyip Erdogan, which many view as a politically driven attempt to eliminate a key rival from the next presidential race. Mayor Ekrem Imamoglu was arrested after a dawn raid on his residence on Wednesday as part of investigations into alleged corruption and terror links, escalating a crackdown on opposition figures and dissenting voices. Several other prominent figures, including two district mayors, were also detained.
