Kosovo police have arrested five Turks working with a group of schools owned by the cleric who Turkish President Recep Tayyip Erdogan blames for an attempted coup two years ago.

In a statement Thursday, the Interior Ministry said their residence permits had been revoked, without providing any reason why.

According to Kosovo law, the ministry can revoke the residence permit for security, criminal, health, public moral or human rights threats.

A source, who has knowledge of the arrests but who declined to be named due to the ongoing operation, told The Associated Press that the five individuals were arrested over expired residence permits and would very likely be deported to Turkey.
