Islamic fighters from the Al-Qaeda-linked Al-Nusra Front drive through the Yarmuk refugee camp on the outskirts of Damascus, on July 28, 2014.

Air strikes by a U.S.-led coalition set up to fight Islamic State targeted the al-Qaeda-linked Nusra Front in northwest Syria overnight, an organization that tracks violence in the Syrian civil war reported on Thursday.

The Syrian Observatory for Human Rights said the air strikes targeted an office and a vehicle used by Nusra Front in Idlib province in northwestern Syria, where last week the al Qaeda-affiliated group routed Western-backed Syrian rebels.

The Observatory also reported the first air strikes against Ahrar al-Sham, another hardline Islamist insurgent group.
