特朗普政府一位高级情报官员在一份记者获取的备忘录中警告称，伊朗已加大针对美国人员的攻击力度，德黑兰针对美国公民的致命阴谋已进入“高级阶段”。
Iran has ramped up efforts to target U.S. personnel, and lethal plots by Tehran against American citizens have reached “advanced stages,” a senior intelligence official in the Trump administration warned in a memo seen by reporters.
国家情报总监杰伊·克莱顿发出这一警报，此前华盛顿上周因伊朗盟友胡塞武装攻势加剧，已缩减其在沙特阿拉伯使团的人员编制。
The alert from Director of National Intelligence Jay Clayton came after Washington scaled back staffing at its mission in Saudi Arabia last week in response to intensified attacks by Iran-allied Houthi forces.
这些针对由伊朗战争引发的近8个月地区冲突一条战线的袭击，恰逢霍尔木兹海峡商业航运遭袭事件增多。
Those attacks on one front of the nearly 8-month-old regional conflict triggered by the Iran war have coincided with a rise in attacks on commercial shipping in the Strait of Hormuz.
本月早些时候，消息人士称，如果美国恢复对伊朗领土的大规模军事打击，伊朗正准备做出更强有力的回应。
Earlier this month, sources said Iran was preparing a more forceful response if the United States resumes large-scale military attacks on its territory.
克莱顿在周五致美国国务卿马尔科·鲁比奥的信函中写道：“具体而言，通过各种渠道，我们收到情报表明，伊朗已大幅增加针对美国人员的攻击努力。”
“Specifically, through various channels, we have received intelligence that Iran has substantially increased efforts to target U.S. personnel,” Clayton wrote to U.S. Secretary of State Marco Rubio in a message dated Friday.
他补充道：“伊朗人针对美国公民的致命阴谋活动，在中东地区及其他一些国家均已进入高级阶段。”
“The lethal plotting efforts by the Iranians against U.S. citizens have reached advanced stages in both the Middle East and certain other countries,” he added.
中央情报局局长约翰·拉特克利夫也被抄送了这份非密级备忘录，该备忘录最早由Axios新闻网报道。
CIA Director John Ratcliffe was also copied in on the unclassified memo, which was first reported by Axios.
美国官员称，国务院周三下令非应急政府雇员及其家属撤离驻沙特阿拉伯外交使团，并计划从该地区其他多个使团撤离家属。
The State Department on Wednesday ordered nonemergency government employees and their family members to leave U.S. diplomatic missions in Saudi Arabia and planned to withdraw family members from a number of other missions in the region, U.S. officials said.
周六，美国国务院更新了海湾和中东十多个国家的旅行警示，包括沙特阿拉伯、卡塔尔、阿拉伯联合酋长国、伊拉克和以色列，理由是来自伊朗结盟的胡塞武装的威胁增加。
On Saturday, the U.S. State Department updated travel advisories for more than a dozen countries across the Gulf and Middle East, including Saudi Arabia, Qatar, the United Arab Emirates, Iraq and Israel, citing an increased threat from Iran-aligned Houthis.
一名美国官员表示：“就大使馆人员编制而言，我们会根据安全环境的新信息持续进行评估。”
“When it comes to our staffing at embassies, we constantly evaluate new information about the security environment,” a U.S. official said.
“胡塞武装袭击的威胁以及伊朗针对美国官员的恐怖阴谋，正在影响我们对该地区处于‘受限行动状态’使馆的人员调整决定，”该官员说。
“The threat of Houthi attacks and of Iranian terror plots targeting U.S. officials are informing our decisions on staffing adjustments for embassies on RO Status in the region,” the official said.
“受限行动状态”使国务院在人事决定上拥有更大灵活性，而无需公开宣布使团地位的变更。
The Restricted Operations Status provides the State Department more flexibility in personnel decisions without having to publicly announce a change in the status of a mission.
伊朗战争距离进入第九个月还有一周时间，已显著拖累了美国总统唐纳德·特朗普在11月3日中期选举前的支持率。
The Iran war is a week away from entering its ninth month and has significantly weighed on the approval ratings of U.S. President Donald Trump ahead of midterm elections on Nov. 3.
