Reuters: Turkey on Wednesday arrested four prosecutors and a gendarme officer for trying to carry out a search of Syria-bound trucks belonging to the state intelligence agency that they suspected of illegally carrying arms for rebels fighting Syria’s government.

Local media said the arrests were part of a crackdown by President Tayyip Erdogan on followers, within the judiciary and police, of a U.S.-based Islamic cleric he accuses of trying to oust him. Seventeen army officers were held last month in the same case.
