周日凌晨在格洛斯特郡英国皇家空军费尔福德基地附近被捕的五名男子已获保释。
Five men arrested in the early hours of Sunday near RAF Fairford, Gloucestershire, have been bailed.
这五名男子均为20多岁的英国公民，最初因涉嫌在美军使用的该基地附近从事恐怖活动而被拘留。
The men, all UK nationals in their 20s, were initially detained on suspicion of terror offences near the base, which is used by the US military.
与此同时，美国国务卿马尔科·鲁比奥表示，该事件“显然有外国势力的介入”。
Meanwhile, US Secretary of State Marco Rubio has said that the incident "clearly involves the hand of a foreign actor".
