Turkish warplanes carried out air strikes against two Islamic State targets in Syrian town of al-Bab and destroyed two armed vehicles on Saturday, the military said in a statement on Sunday.
NATO member Turkey launched an incursion into Syria, dubbed "Euphrates Shield", more than four months ago to drive Islamic State away from its border. Turkish-backed Syrian rebels have besieged al-Bab for several weeks as part of the offensive.
With Euphrates Shield, Turkey aims to prevent the Kurdish YPG militia from joining up cantons it already controls along the Turkish border, fearing that would embolden Kurdish separatism inside Turkey.
Turkish-backed forces have so far secured 1,860 square km (720 square miles) of territory in Syria, it said, reaching as far as the northern and western borders of al-Bab.
