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.

Dozens of demonstrators marched through central Istanbul Thursday protesting the arrest of the city’s mayor. The demonstrations began last week following the arrest of Istanbul Mayor Ekrem Imamoglu, a key rival to President Recep Tayyip Erdogan.
