Turkey beefs up forces on Syria border

Several tanks, military transport vehicles and at least 10 artillery units including cannons were sent to Oguzeli and Karkamis in southeastern Turkey, state news agency Anadolu reported.

The latest deployment came as Turkish forces tightened their grip around the IS bastion of Al-Bab in northern Syria, as Ankara-backed Syrian rebels and Turkish troops pressed a fierce assault to capture the town.

Sixteen Turkish soldiers were killed by IS in the battle for the flashpoint town Wednesday -- Ankara's biggest loss so far since it launched its incursion into Syria in August.

The Turkish army said it killed 12 IS jihadists Sunday near Al-Bab, though it was not possible to independently verify the claim.

A Britain-based monitoring group meanwhile said on Friday that at least 88 civilians had been killed in 24 hours of Turkish air strikes on Al-Bab, including 21 children.

Syrian President Recep Tayyip Erdogan on Saturday said "Al-Bab is nearly finished", and reiterated a previous vow that Turkish forces would head next to the town of Manbij, a former bastion of IS that is now under the control of US-backed, Kurdish-led militia.

Ankara views Syria's Kurdish forces -- which have played a lead role in the battle against IS -- as "terrorists" linked to a 30-year Kurdish insurgency in Turkey.

It has vowed not to take part in any international offensive to reclaim Raqa, IS's main bastion in northern Syria, should Kurdish fighters take part.

Erdogan will discuss the issue with the incoming US administration after President-elect Donald Trump is inaugurated in January, Erdogan said.
