Kurdish fighters have accused Turkey of deliberately targeting them instead of focusing on the "terrorists" of the so-called Islamic State.
The Kurdish People's Protection Unit (YPG) militia claimed the Turkish army had shelled its positions in a village on the outskirts of the IS-held town of Jarablus, in north-western Syria.
In a statement, the fighters urged Ankara to halt its "aggression" against their group.
It comes after Turkish F-16 fighter jets reportedly hit Kurdistan Workers Party (PKK) targets in northern Iraq yesterday, as part of an ongoing operation against both Kurdish militants and Islamic State.
