库尔德民兵正在围攻伊斯兰国组织在靠近土耳其边界的叙利亚境内所占领的一个重镇。
收复塔尔艾卜耶德将能切断伊斯兰国战斗人员的运输和补给路线。
由于预计库尔德人和激进分子之间将爆发激战，成千上万叙利亚人已经逃离那个地区。
星期天，这些叙利亚人得以跨境进入土耳其，但在此之前，他们遭到一些土耳其军人的拦阻。一名记者说，几名军人让难民跨境进入土耳其；但另一名记者说，他看到人们穿过边境栅栏进入土耳其。
战事已迫使100多万叙利亚难民涌入土耳其。土耳其总统埃尔多安担心难民危机可能会恶化。
他星期天还说，他担心，两个库尔德组织 - 民主联盟党以及被视为非法团体的库尔德工人党 - 会在土耳其与叙利亚的交界地带做大得势。
库尔德人长期以来一直在打游击战，对抗土耳其政府，谋求建立独立的库尔德国家。埃尔多安认为，美国领导的联军在叙利亚境内的空袭会为库尔德人开辟疆土。
也是在星期天，叙利亚城市霍姆斯两个政府控制的社区发生汽车炸弹袭击，造成27人受伤。目前还没有人声称对袭击负责。
霍姆斯是四年前发生试图推翻叙利亚总统阿萨德暴动的城市之一，也经常是炸弹袭击的目标城市。
Kurdish militias are closing in on an important Islamic State-held town in Syria near the Turkish border.
Retaking Tal Abyad could cut off a transit and supply route for Islamic State fighters.
Thousands of Syrian civilians have fled the area, anticipating fierce fighting between the Kurds and the militants.
Syrians managed to cross into Turkey Sunday after some Turkish soldiers kept them from entering. One reporter said several soldiers let the refugees cross while another journalist said he saw people cutting through a fence.
Fighting has driven more than a million Syrian refugees into Turkey and Turkish President Recep Tayyip Erdogan is worried the refugee crisis could worsen.
He also said Sunday he is concerned that two Kurdish groups - the Democratic Union Party and the outlawed Kurdistan Workers Party - could gain ground along Turkey's border with Syria.
Kurds have long fought a guerilla war against Turkey for an independent Kurdish state. Mr. Erdogan believes U.S.-led coalition airstrikes along just inside Syria could carve out territory for the Kurds.
Also in Syria Sunday, car bombs wounded 27 people in two government-controlled neighborhoods in the city of Homs. No one has claimed responsibility.
Homs is one of the cities where the uprising against Syrian President Bashar al-Assad began four years ago and has been a frequent target of bombings.
