REPUBLIKA.CO.ID, BEIRUT - Air strikes overnight hit Islamic State-held territory in Syria near the Turkish border, near an area that tens of thousands of Kurds have fled as the militant group advanced, an organization that tracks the Syrian war said on Wednesday.

Rami Abdulrahman, who runs the Syrian Observatory for Human Rights, said the warplanes that carried out the raids around 30-35 km (19-22 miles) west of the city of Kobani, also known as Ayn al-Arab, had come from the direction of Turkey.

There was no other confirmation of air strikes in the area and Reuters could not independently verify the report.

Abdulrahman said it was not clear which country had carried out the strikes, although the planes were not believed to be from the Syrian air force, he said. Abdulrahman's Observatory gathers its information from a network of sources across Syria.

A US-led alliance started air strikes on Islamic State in Syria on Tuesday. Islamic State, which has captured land in Syria and Iraq, launched an offensive against the predominantly Kurdish town of Kobani last week, forcing more than 130,000 Syrian Kurds to flee.
