Turkey has sent more tanks into northern Syria, in an operation against the Islamic State terror group. Local media reported that the tanks crossed the border near the Turkish town of Kilis and firing was heard, with plumes of smoke rising on Syrian territory.

Civilians were seen fleeing as the Turkish military advanced. Syrian rebels backed by Turkey said they had recaptured at least eight villages from IS in the area. The tanks’ advance was supported by artillery, targeting IS positions. The reports said about 20 tanks, five armoured personnel carriers and other armoured vehicles were involved in the assault.

The incursion took place south-west of Jarablus, where Turkey last week launched its first major incursion into Syria since the conflict started.
