一连串炸弹威胁扰乱了整个欧洲的客运航班，据信是一场恶作剧行动，导致飞机停飞、备降，并促使战斗机紧急升空拦截。
A string of bomb threats roiled passenger flights across Europe in a suspected hoax campaign that grounded aircraft, led to diversions and prompted the scrambling of jet fighters.
受影响航班超过十余班次，标志着本周第二日出现中断，此前周二发生类似的恶作剧炸弹威胁，涉及至少七个航班。
More than a dozen flights were affected, marking a second day of disruption this week after a similar spate of hoax bomb threats that involved at least seven flights Tuesday.
据知情人士透露，周四有两起备降事件是由一封发往罗马主要机场的电子邮件引发的，该邮件声称来自一个边缘极端民族主义俄罗斯组织。
Two of the diversions Thursday were triggered by an email sent to Rome’s primary airport purporting to be from a fringe ultranationalist Russian group, according to a person familiar with the matter.
知情人士称，邮件声称两枚爆炸装置已被安置在两个飞往意大利首都的航班上。
The email alleged that explosives had been placed on two flights en route to the Italian capital, the person said.
