ROUGH CUT (NO REPORTER NARRATION)
The United States and its allies launched a new round of air strikes on Sunday (November 23) against Islamic State fighters.
Plumes of smoke rose from the Syrian border town of Kobani as Turkish troops kept a close eye on the embattled town from near the border.
Explosions were heard on the Turkish border with Syria and at least one fighter jet was seen flying overhead.
The battle for Kobani - known in Arabic as Ayn al-Arab - has become a test of the U.S.-led coalition's ability to stop Islamic State's advance.
Islamic State has been trying to take control of the town for more than two months in an assault that has driven tens of thousands of Kurdish civilians over the border into Turkey and drawn strikes by U.S.-led forces.
The defense of Kobani has drawn in Kurdish peshmerga fighters from Iraq as well as Syrian rebel fighters.
