US-led strikes hit Syria's Raqa, Aleppo provinces

Fresh US-led strikes hit Islamic State group targets in Syria overnight, both in its Raqa province stronghold and in Aleppo province further west, the Syrian Observatory for Human Rights said on Monday.

In Aleppo province, the strikes hit targets around the IS-held town of Minbej, including a complex of grain silos and a mill that was being operated by civilians.

The strikes also hit a local IS headquarters between Minbej and the town of Jarabulus further north.

In Raqa province, strikes hit the outskirts of Raqa city, the de facto headquarters of IS in Syria, hitting at least one checkpoint belonging to the group.

The coalition also carried out strikes around the town of Tal Abyad, on the border with Turkey, hitting a local headquarters by IS militants.

The latest strikes came after the coalition struck the entrance of the country's main gas plant in the eastern city of Deir Ezzor in an apparent warning to IS militants to abandon the facility.

The plant is the largest in Syria and feeds a key power station in regime-held Homs province.

If it stopped functioning, several provinces, including Deir Ezzor, would be without electricity.
