"The attack on the Kurdish neighbourhoods in Aleppo and the approach and attitude of state officials towards our movement sabotage the 'Peace and Democratic Society' process," said a PKK statement carried by the Firat news agency.

The clashes erupted last week after negotiations stalled on integrating the Kurds' de facto autonomous administration and forces into Syria's new government.

By Sunday, Syrian forces were in full control of Aleppo after taking over the city's Kurdish neighbourhoods and evacuating fighters there to Kurdish autonomous areas following days of deadly clashes.

Turkey, which views Kurdish fighters in Syria as a terror group affiliated with the PKK blacklisted by Ankara and its Western allies, lauded Syria's operation as "against terrorist organisations".

The Aleppo attacks "call into question the ceasefire between our movement and Turkey and the ongoing 'Peace and Democratic Society' process based on it," the PKK said.

"We have fulfilled our responsibilities in the 'Peace and Democratic Society' process without hesitation and with courage," it said urging Turkey's ruling party and its nationalist MHP ally to "refrain from steps and practices that sabotage the process."
