Syria was on the brink of a fresh round of conflict on Tuesday as Turkish-backed fighters advanced on the Kurdish-majority city of Kobane.

Fighters with the Syrian National Army (SNA), a rebel group supported by Turkey, crossed the Euphrates in the direction of Kobane under the protection of Turkish jets.

Turkey’s military intelligence agency also said it had destroyed 12 military trucks, two tanks and ammunition stores after they fell into the hands of the YPG, a Kurdish militia.
