Turkey said on Sunday it had killed 23 Kurdish rebels in northern Syria, the latest in a series of strikes against them which have continued since US President Donald Trump took office last month.
The defence ministry said they belonged to the Syrian Kurdish YPG militia and the outlawed Kurdistan Workers Party, or PKK.
Turkey regards the PKK and YPG to be identical, while the United States views them as separate groups, having banned the PKK as terrorists but recruited the YPG as its main allies in Syria in the campaign against IS.
Turkey has long called on Washington to withdraw support for the YPG, expressing hope that Trump would revise the policy of the previous administration of President Joe Biden.
Turkish forces and their allies in Syria have repeatedly fought with Kurdish rebels there since the toppling of Syrian President Bashar Al-Assad in December.
Turkey has said that the Syrian Democratic Forces, or SDF - a US-backed umbrella group that includes the Kurdish YPG - must disarm or face military intervention.
Under the Biden administration the United States has had 2,000 troops in Syria fighting alongside the SDF and YPG.
