美国民众星期四庆祝传统节日感恩节，亲友欢聚一堂，享受美味佳肴，观看游行或美式足球比赛，而且对很多人来说，这也是假期购物季节的开始。
但是2017年，包括纽约曼哈顿的梅西感恩节大游行在内的很多庆祝活动都将加强保安。
纽约的梅西感恩节大游行通常会吸引20万人观看。而就在不久前，一位乌兹别克移民驾驶租来的卡车在曼哈顿的自行车道上横冲直撞，撞死8人。
纽约官员说，保安措施包括部署狙击手、满载沙子的自卸卡车和专门查找炸弹的警犬。
纽约警察局说，虽然目前没有任何经证实的威胁，但是将在游行4公里长的曼哈顿街道上部署数以千计的警察。梅西大游行定于美国东部时间上午9点开始。
Americans will celebrate Thanksgiving Thursday as they traditionally do — gathering with family and friends around tables groaning with food, watching parades and football games, and, for many, starting their holiday shopping.
But the 2017 celebrations, including the iconic Macy's Thanksgiving Day Parade in Manhattan, will be under close scrutiny.
The parade, which attracts about 200,000 spectators, comes just weeks after an Uzbek migrant is accused of driving a rented truck onto a crowded bike path, killing eight people.
New York officials said security will include police sharpshooters, as well as sand-laden dump trucks and bomb-sniffing dogs.
While they have verified no credible threats, the New York City Police Department said it is deploying thousands of police officers along the 4-kilometer (2.5-mile) route through Manhattan. The parade beings at 9 a.m. EST (1400 UTC).
