Missile strikes in northern Syria near the Turkish border killed one person and injured at least 11 others Friday, Turkish state media and a source from the Turkish-backed faction that controls the region said.
Explosions rocked local oil refineries near the towns of al-Bab and Jarablus, sparking large fires, a witness and Turkey's state-owned Anadolu news agency said.
The source in the National Army, which controls swaths of northwest Syria where Turkish troops have a presence, said missile strikes had caused the blasts, wounding 11 people.
Anadolu said they were ballistic missiles and it was not clear who carried out the strikes, which it said injured 18 people.
Turkey has backed fighters who sought to overthrow Bashar al-Assad, but the Syrian president, with Russian and Iranian help, has driven back the insurgents to a pocket in the northwest of the country.
