Protests have erupted in Turkey following the arrest of popular Istanbul mayor Ekrem Imamoglu, who was set to run in the next presidential election. Thousands of people have taken to the streets, accusing President Recep Tayyip Erdogan of attempting to remove his main opponent. Erdogan's actions are part of a broader crackdown on opposition figures in the country, with over 2,000 people arrested since March 19. The protests continue to escalate, posing a challenge to Erdogan's political dominance.
