Kurdish fighters are suspected of firing rockets from northern Syria, after the Turkish air force conducted
air strikes on positions in Syria held by the Kurdish People’s Protection Units, or the YPG, on Sunday.
The raids in Syria killed at least 31 people, according to the monitoring group, the Syrian Observatory for Human Rights.
Turkey accuses the PKK of being behind a bombing in Istanbul that killed six people on November 13 and considers the YPG the PKK’s affiliate in Syria.
