Missile hit oil refineries in northern Syria, killing three
Missile strikes in Turkish controlled parts of northern Syria on Friday killed three and injured 28, Turkish state-run Anadolu agency reported.
The attacks targeted oil refineries near the towns of al-Bab and Jarablus, causing violent explosions after several fuel tankers caught fire.
It was not yet clear who carried out the attacks, which involved ballistic missiles, Anadolu said.
Turkey has controlled al-Bab and Jarablus since launching a cross-border incursion against the Islamic State (ISIS) in 2016, a move aimed at stopping the cities from falling to the Kurdish-led Syrian Democratic Forces (SDF).
Tensions remain high in the region, where forces loyal to the Assad regime have threatened to launch a Russian-backed offensive against rebel groups in the nearby province of Idlib.
Turkey strongly opposes an attack in Idlib, which could push a fresh wave of refugees across the Turkish border.
Negotiations between Turkey and Russia over the future of the province have repeatedly stalled.
Last February, 33 Turkish soldiers deployed to monitor the situation in Idlib were killed by Assad regime airstrikes.
Russia, which provides air support to Assad regime forces, denied responsibility for the Idlib strikes.
