Turkey vowed to root out allies of the U.S.-based cleric it blames for an abortive coup last week, widening a purge of the army, police and judiciary on Tuesday to universities and schools, the intelligence agency and religious authorities.

Around 50,000 soldiers, police, judges, civil servants and teachers have been suspended or detained since the coup attempt, stirring tensions across the country of 80 million that borders Syria's chaos and is a Western ally against Islamic State.

"This parallel terrorist organization will no longer be an effective pawn for any country," Prime Minister Binali Yildirim said, referring to what the government has long alleged is a state within a state controlled by followers of Fethullah Gulen.
