Fresh from facing down a coup attempt this weekend, Turkish President Recep Tayyip Erdogan has hammered the police, judiciary and civil service so hard that some analysts warn of lasting damage to the state.

Around 50,000 officials have been sacked, including judges, police commanders and university deans.

The education ministry has revoked the licences of 21,000 teachers working in private institutions and banned other teachers from traveling abroad, Turkish media said Wednesday.
