More than 1,100 people, including some journalists, were detained in protests against Turkish President Erdogan after the arrest of his rival, Istanbul Mayor Ekrem Imamoglu.

Turkish President Tayyip Erdogan said on Monday that protests over the jailing of Istanbul's mayor had become a "movement of violence" and that the main opposition party would be held accountable for injured police officers and damage to property.

Analysts say a convergence of international factors gave Turkish President Recep Tayyip Erdogan the opportunity to try to neutralize Istanbul Mayor Ekrem Imamoglu, the main threat to him in elections due to be held in 2028.
