ANKARA, June 6 (Xinhua) -- Turkey will "respond adequately" against any threats to its security springing from the operation to recapture Raqqa, said Prime Minister Binali Yildirim on Tuesday.

"We will never allow any situation to threaten Turkey. If we face any threat to our security from Raqqa or any other place in the region, we will respond immediately and adequately," Yildirim said when addressing the ruling Justice and Development Party deputies at the party's parliamentary group meeting, reported local private channel NTV.

"Turkey's awareness and red lines are clear and they will never change," Yildirim stressed.

The prime minister stated that Turkey will be closely monitoring any situation which could develop from the operation as well as take all necessary precautions.

The operation to recapture Raqqa, the Islamic State's de-facto capital in Syria, began on June 2 with an assault by the U.S.-backed Syrian Democratic Forces (SDF), the U.S., the EU and the Syrian affiliate of the Kurdistan Workers' Party (PKK), listed as a terrorist organization by Turkey.

The U.S. provided the People's Protection Units (YPG) with weapons following a presidential order signed by President Donald Trump mid-May, ignoring the warning from its Turkish NATO ally.

The U.S. has allayed Turkey's concerns however, stating that the weapons will not be used against Turkey by terrorist groups operating within the country.

The majority of SDF forces are comprised of the YPG, the armed wing of the PKK's Syrian offshoot.

"Supporting terrorist groups is incompatible with being an ally to Turkey," Yildirim said, adding "we must work on a common understanding when combating regional terrorist groups, without exception."
