库尔德官员表示，伊斯兰国极端组织武装星期六从3个战线轰击叙利亚边境城镇柯巴尼。
这是激进分子试图夺取该镇的最新攻势。库尔德武装在美国领导的国际空袭行动的支援下，目前固守这个城镇。
大约16万人为躲避柯巴尼周边地区的战事，越过边界逃入土耳其。这里的冲突据说转移了对叙利亚内战的关注。
柯巴尼及其附近地区自9月中以来一直受到伊斯兰国组织武装的攻击，试图在他们位于叙利亚阿勒颇的阵地和以东方向拉卡的据点之间打开一条通道。伊斯兰国组织武装已经占领了几十个附近的库尔德村庄。
另外，美国副总统拜登为其有关评论向土耳其总统埃尔多安道歉。拜登曾表示，土耳其曾允许伊斯兰武装分子穿过其边境进入叙利亚，并帮助提供武器给激进组织。
Kurdish officials say Islamic State forces shelled the Syrian border town of Kobani from three fronts Saturday.
The attacks are the latest attempts by militants to take the town, defended by Kurdish forces backed by U.S.-led airstrikes.
An estimated 160,000 people have fled across the border into Turkey to escape the fighting around Kobani; a conflict now said to be overshadowing Syria's wider civil war.
Kobani and its surrounding areas have been under attack since mid-September by Islamic State fighters trying to open a direct link between their positions in the Syrian province of Aleppo and their stronghold of Raqqa, to the east. The Islamic State group has captured dozens of nearby Kurdish villages.
In another development, U.S. Vice President Joe Biden has apologized to Turkish President Recep Tayyip Erdogan for comments suggesting Turkey had allowed Islamic fighters to pass through its border into Syria and helped arm militant groups.
