At least 37 people have been detained in Turkey for criticizing the arrest of Istanbul Mayor Ekrem İmamoğlu, who is seen as a rival to President Erdoğan. İmamoğlu faces corruption charges, which his supporters claim are politically motivated. Protests erupted despite a ban on demonstrations, and the Turkish Interior Minister announced arrests for 'provocative' online posts. İmamoğlu's recent arrest comes just before an internal party election where he was expected to be the presidential candidate. His diploma was also nullified, raising concerns about his eligibility. International leaders, including German Chancellor Olaf Scholz, have condemned the situation.
