Turkish authorities arrested dozens for 'provocative' social media posts following the detention of Istanbul's mayor, Ekrem Imamoglu, who is a rival of President Erdogan. His arrest has led to protests in Istanbul and Ankara, with critics labeling it a 'coup'. The government has restricted social media usage and police clashed with demonstrators. The arrests are seen as politically motivated, coinciding with Imamoglu's expected candidacy for the 2028 elections. Teljes cikk (bbc.com europe)
