"There is no reason why the bomb that exploded in Ankara cannot explode in Brussels, in any other European city," Erdogan said during a Friday speech in the coastal town of Çanakkale. "The snakes you are sleeping with can bite you any time," he said using the word 'snakes' as a metaphor for the supporters of the Kurdistan Workers’ Party (PKK).

His remarks came after supporters of the PKK militant group were allowed to set up protest tents outside the European Union building in Brussels, where EU-Turkey meetings on refugees were held on Thursday and Friday.

European countries are “dancing in a minefield” by directly or indirectly backing militant groups, Erdogan noted.

The Kurdistan Freedom Falcons (TAK) militant group, which is affiliated to the PKK, claimed responsibility for the car bombing in the Turkish capital on March 13 that killed 37 people.

Ankara has been engaged in a large-scale campaign against the PKK in its Kurdish-majority southeastern region over the past few months. The Turkish military has also been conducting offensive operations against the positions of the group in northern Iraq.

The campaign began following a deadly July 2015 bombing in the southern Turkish town of Suruç. More than 30 people died in the attack, which the Turkish government blamed on the ISIS Takfiri terrorist group.

After the bombing, the PKK militants, who accuse the government in Ankara of supporting ISIS, carried out a number of reprisal attacks against Turkish police and security forces, prompting the Turkish military operations.

Ankara’s attacks against the PKK voided a shaky ceasefire declared in 2013 between the government and the militants, who have been fighting for an autonomous Kurdish region inside Turkey since 1980s, Press TV reported.
