据美国媒体报道，美国情报专家认为，俄罗斯是上周一起针对德国机场的袭击事件的幕后黑手，该袭击使用了一架满载爆炸物的无人机，而柏林方面对可能的肇事者保持沉默。
Last week’s security emergency prompted(促使，引起) the interior minister, Alexander Dobrindt, to break off(中断，突然停止) his summer holiday in Italy and rush to the scene(赶往现场) in the eastern city of Leipzig, as he spoke of a “new level of danger” for Germany.
上周的安全紧急事件促使内政部长亚历山大·多布林特中断在意大利的暑假，赶往东部城市莱比锡的现场，他谈到了德国面临的“新的危险级别”。
Dobrindt called the incident, in which a quadcopter(四轴飞行器) with semtex(塞姆汀塑胶炸药) plastic explosives attached was found next to a Ukrainian cargo plane at the major shipping and military hub, part of a “professional hybrid threat(混合威胁) scenario” by a well-equipped foreign actor(行为体，参与者).
多布林特称，这起事件——一架装有塞姆汀塑胶炸药的四轴飞行器在主要航运和军事枢纽的一架乌克兰货机旁被发现——是装备精良的外部势力实施的“专业混合威胁场景”的一部分。
