Turkish President Recep Tayyip Erdogan urged Europe to get behind his campaign against Kurdish separatists Thursday, condemning the latest attack against Turkish forces.
"We have regrettably lost seven members of the security forces who have lost their lives and we have 14 injured," he told an audience in Washington.
"We cannot tolerate this anymore. European countries and other countries, I hope they can see the true face of terrorists in these attacks."
Earlier, Turkish officials said six police officers were killed and at least 23 people wounded in a bomb attack on their vehicle in the Kurdish-majority city of Diyarbakir.
Erdogan told the audience at the Brookings Institution think tank that the whole world must come together to fight the scourge of terrorism.
And he insisted that the Kurdish rebels that his forces are fighting are as dangerous as the fighters of the Islamic State group, which has become the West's main target.
In Syria, US-led coalition forces are assisting the YPG, a Kurdish militia which Ankara regards as a subsidiary of the PKK group, against the IS group.
"YPG is a gang of terrorists. Another group is fighting against Daesh so they are 'good terrorists'?" he demanded, using an Arabic abbreviation for IS.
"This is unacceptable to us. These are the organizations that are auxiliaries of the PKK."
