Four Turkish troops wounded in attacks in Syria, Ankara says

ISTANBUL (Reuters) - Four Turkish soldiers were wounded in artillery and rocket attacks by Kurdish militants on bases in northern Syria, prompting a counter attack, Ankara said on Sunday.

Turkey's defence ministry said the attacks were carried out by the Syrian Kurdish YPG militia, which spearheads the U.S.-allied Syrian Democratic Forces (SDF), and also the Kurdistan Workers' Party (PKK), which Turkey and Western nations deem a terrorist group.
