伦敦9月29日电——英国反恐警方周二表示，在针对一起涉嫌图谋袭击美国空军用于打击伊朗的英国空军基地的调查中，未发现任何简易爆炸装置。
LONDON, Sept 29 - Britain's counter-terrorism police said on Tuesday that no improvised explosive devices had been found as part of an investigation into a suspected plot targeting a British airbase used by US forces to strike Iran.
警方称，在对现场车辆进行搜查时缴获了一定数量的汽油。他们补充说，警方已对伦敦的房产进行了搜查，拉斐尔德空军基地（RAF Fairford）周围的调查现场正在缩减规模，预计将于周三全面关闭。
Police said a quantity of petrol had been recovered during searches of vehicles at the scene. They added that searches of properties in London had been carried out, and investigative scenes around RAF Fairford were being scaled back and were expected to close completely by Wednesday.
周日被捕的五名男子在获保释后仍在接受调查，警方称释放他们的决定是基于调查需要。
Five men arrested on Sunday remain under investigation after being released on bail, with police saying the decision to release them was an investigative one.
国家反恐警务负责人劳伦斯·泰勒（Laurence Taylor）表示：“我理解这一进展会令许多人感到意外，但我愿重申，这是一个调查决定，是建立在经验和对警务权力的审慎考量之上的。”
"I understand why this development will have come as a surprise to many, but I'd like to reiterate that it was investigative decision, and one which is grounded in experience and careful consideration of policing powers," Laurence Taylor, head of national counter terrorism policing, said.
