ANKARA (Reuters) – Turkish President Tayyip Erdogan said on Thursday Germany had become a haven for terrorists and would be “judged by history”, accusing it of failing to extradite supporters of a U.S.-based cleric Ankara blames for July’s failed military coup.

He said Germany had long harbored militants from the Kurdistan Workers Party (PKK), which has waged a three-decade insurgency for Kurdish autonomy, and far-leftists from the DHKP-C, which has carried out armed attacks in Turkey.

“We don’t have any expectations from Germany but you will be judged in history for abetting terrorism … Germany has become an important haven for terrorists,” Erdogan told a ceremony at his palace in the capital Ankara.

“We are concerned that Germany, which has protected the PKK and DHKP-C for years, has become the backyard of the Gulenist terror organization.”
