Turkish authorities detained and deported BBC correspondent Mark Lowen​ and arrested other journalists amid the largest nationwide protests in a decade.

To pressure President Recep Tayyip Erdogan over the jailing of his top rival, the opposition wants Turks to boycott companies that back Mr. Erdogan and plans to organize a protest this weekend.

Istanbul's opposition-run municipal council on Wednesday elected an interim mayor to run the city, broadcaster NTV said, after mayor Ekrem Imamoglu was jailed pending trial over graft charges that he and his supporters deny and call politicised.
