Turkish security forces confiscated one tonne of marijuana in the southeastern province of Batman on Monday.

Anti-narcotic police teams conducted an operation against the PKK terror group, detaining one suspect, said a source who asked not to be named due to restrictions on speaking to the media.

The operation came less than three weeks after security forces seized 5.5 million cannabis plants and 63 kilograms of hashish in Diyarbakir province.
