The village of Suran is located 16km (10 miles) southwest of al-Bab, which rebels supported by Turkish jets, armor and special forces are attempting to capture from Daesh after reaching its outskirts a month ago, Reuters reported.
Turkey which has long been one of the biggest supporters of anti-Assad militants, claims its entry into Syria last summer was aimed at pushing Daesh from its border and at stopping Kurdish groups linking two enclaves they control along the frontier.
After militants lost their pocket of territory in Aleppo in December, Turkey and Russia brokered a ceasefire and peace talks in Syria between the government and militants.
Last week, Turkey's Deputy Prime Minister Mehmet Simsek appeared to soften Ankara's position against Assad, saying it was no longer realistic to demand a resolution of the conflict without his involvement.
