The Syrian army destroyed Islamic State positions northeast of the northern city of Aleppo on Wednesday, state media said, after US-led forces carried out air strikes against the group for a second day.

Syrian state television said the military hit Islamic State militants between the towns of al-Bab and al-Qabasein and had "eliminated a number of terrorists".

After the US-led coalition began its strikes on Tuesday, the Syrian government said it would continue to confront Islamic State and other militants.
