乌克兰国际航空公司752航班是一架波音737-800飞机，从德黑兰伊玛目霍梅尼国际机场飞往基辅鲍里斯皮尔国际机场，周二起飞后几分钟，不久后停止传输数据伊朗发射了导弹驻扎在邻近伊拉克的美国和盟军的军事基地。三名官员告诉记者，这架飞机被俄罗斯建造的托尔-M1地对空导弹系统击中，北约称之为“挑战书”新闻周刊。

一名五角大楼官员和一名美国高级情报官员告诉记者新闻周刊五角大楼的评估是这一事件是偶然的。伊朗的防空系统很可能在该国导弹袭击后处于活跃状态美国上周的杀戮消息来源称，革命卫队圣城部队指挥官少将·卡西姆·苏莱曼尼。

“嗯，我有我的怀疑，”唐纳德·特朗普总统在白宫告诉记者新闻周刊美国报告。"它在一个相当恶劣的街区飞行，可能有人搞错了。"

美国中央司令部拒绝就此事发表评论新闻周刊。国家安全委员会和国务院尚未做出回应。

船上的176人中，82人是伊朗人，63人是加拿大人，11人是乌克兰人(包括9名机组人员)，还有10名瑞典人、7名阿富汗人和3名德国人。无人幸存。

1月8日凌晨，一架载有176人的乌克兰飞机在伊朗首都德黑兰伊玛目霍梅尼国际机场附近坠毁，机上所有人遇难，救援队在废墟中工作。

伊朗半官方媒体首次报道了这一事件，援引伊朗红新月会的评估称，最初的原因似乎是机械故障。乌克兰驻德黑兰大使馆在一份声明中同意这一观点，但后来撤回了这一观点，基辅警告不要从初步评估中得出结论。

周三，照片开始流传，似乎是一枚Tor M-1导弹的碎片，据说是在德黑兰西南郊区发现的。乌克兰安全委员会秘书奥莱克西·丹尼洛夫周四在一份声明中表示，与Tor M-1系统的接触是乌克兰和伊朗官员会面时乌克兰正在调查的飞机失事的潜在原因之一。

其他潜在情况包括与无人驾驶飞行器或其他飞行物体的碰撞、技术故障和恐怖袭击。

伊朗民航组织负责人也已邀请加拿大和瑞典在事故调查中合作，然而，负责人阿里·阿布扎德强调，他不会交出飞机的黑色box⁠—which可能会提供这次注定失败的飞行的最后moments⁠—to美国的细节。

伊朗政府后来发表声明，申明将遵守国际民用航空组织(International Civil Aviation Organization)的规定，除了邀请外国代表参与调查之外，该国还将允许波音公司派代表检查黑匣子，阿布扎德称黑匣子已经损坏。

阿布扎德周四早些时候否认了导弹袭击击落乌克兰国际航空公司752航班的猜测。在一份声明中，他说这个结果“在科学上是不可能的，这样的谣言毫无意义。”

周四，加拿大外交部长弗朗索瓦-菲利普·香槟罕见地与伊朗外长穆罕默德·贾瓦德·扎里夫进行了交谈，他“向扎里夫强调，加拿大官员需要迅速获准进入伊朗，提供领事服务，帮助确认死者身份，并参与坠机事件的调查。”

香槟说，“加拿大和加拿大有许多问题需要回答。”

当被问及加拿大政府是否正在考虑或主导一枚防空导弹击落乌克兰国际航空公司752航班的可能性时，全球事务发言人克里斯汀娜·道兹表示，她的办公室将不得不返回新闻周刊在这件事上。

周四晚些时候，加拿大总理贾斯廷·特鲁多证实，他的官员已经收到“来自多方面的情报，包括我们的盟友和我们自己的情报”，表明“这架飞机是被伊朗地对空导弹击落的”

“这很可能是无意的，”他补充道。“这一新信息加强了对此事进行彻底调查的必要性。加拿大正与其盟国合作，确保进行彻底和可信的调查，以确定这次致命坠机的原因。”

伊朗对美国军队占据的伊拉克军事阵地发动导弹袭击，这是涉及这两个大国的一系列暴力事件中的最新一起。华盛顿将针对美国人员的火箭弹袭击归咎于德黑兰支持的伊拉克民兵组织，并以针对这些战斗人员的致命边境袭击作为回应，导致美国大使馆发生暴力抗议，事件发生后不久，苏莱曼尼被暗杀。

这两个敌人已经争斗了40年，但很少直接面对对方。美国和伊朗的争端可以追溯到1979年的伊斯兰革命，这场革命揭露了西方支持的君主制，外交官在华盛顿驻德黑兰大使馆被扣为人质长达14个多月。

第二年，美国支持伊拉克入侵伊朗，这是一场持续了八年的致命战争，并伴随着波斯湾的所谓“油轮战”，双方的敌意才进一步加深。冲突结束前不久，一艘美国海军军舰击落了一架伊朗客机，伊朗航空公司655航班1988年，在一次导弹袭击中，机上290人全部遇难。

这位美国高级情报官员告诉记者:“[五角大楼不想升级，尤其是因为我们早就有自己的事件。”新闻周刊与1988年的事件有关，该事件仍然困扰着德黑兰和华盛顿在最重要的地缘政治热点之一陷入困境的关系。

波斯湾对全球石油流动至关重要。特朗普决定退出2015年的一项核协议，该协议给予伊朗制裁减免，以换取遏制其核活动。此后，动荡如今又回到了这个关键地区及其水路。在最近伊朗导弹袭击后，总统选择了缓和局势，扩大制裁，但也呼吁伊斯兰共和国放弃对激进组织的支持，停止寻求核武器——德黑兰的东西一直否认想要

IRANIAN MISSILE SYSTEM SHOT DOWN UKRAINE FLIGHT, PROBABLY BY MISTAKE, SOURCES SAY

The Ukrainian flight that crashed just outside the Iranian capital of Tehran was struck by an anti-aircraft missile system, a Pentagon official, a senior U.S. intelligence official and an Iraqi intelligence official told Newsweek. None of the officials was authorized to speak publicly on the matter.

Ukraine International Airlines Flight 752, a Boeing 737–800 en route from Tehran Imam Khomeini International Airpot to Kyiv's Boryspil International Airport, stopped transmitting data Tuesday just minutes after takeoff and not long after Iran launched missiles at military bases housing U.S. and allied forces in neighboring Iraq. The aircraft is believed to have been struck by a Russia-built Tor-M1 surface-to-air missile system, known to NATO as Gauntlet, the three officials told Newsweek.

One Pentagon and one U.S. senior intelligence official told Newsweek that the Pentagon's assessment is that the incident was accidental. Iran's anti-aircraft systems were likely active following the country's missile attack, which came in response to the U.S. killing last week of Revolutionary Guard Quds Force commander Major General Qassem Soleimani, sources said.

"Well, I have my suspicions," President Donald Trump told reporters at the White House following Newsweek's report. "It was flying in a pretty rough neighborhood and someone could have made a mistake."

U.S. Central Command declined to comment on the matter when contacted by Newsweek. The National Security Council and the State Department have not yet responded.

Of the 176 people on board, 82 were Iranian, 63 were Canadian and 11 were Ukrainian (including nine crewmembers), along with 10 Swedish, seven Afghan and three German nationals. None survived.

Rescue teams work amidst debris after a Ukrainian plane carrying 176 people crashed near Imam Khomeini International Airport in the Iranian capital Tehran early in the morning on January 8, killing everyone on board.

The incident was first reported by Iranian semi-official media outlets, which cited the country's Red Crescent Society as assessing that the initial cause appeared to be mechanical failure. The Ukrainian embassy in Tehran shared this view in a statement, but later retracted it, with Kyiv warning not to draw conclusions from preliminary assessments.

Images began to circulate Wednesday of what appeared to be fragments of a Tor M-1 missile said to have been found in a suburb southwest of Tehran. Ukraine Security Council Secretary Oleksiy Danylov said Thursday in a statement that contact with a Tor M-1 system was among the potential causes for the plane's destruction that his country was looking into as Ukrainian and Iranian officials met.

Other potential scenarios involved a collision with an unmanned aerial vehicle (UAV) or another flying object, technical malfunction and a terrorist attack.

The Civil Aviation Organization of Iran Chief has also invited Canada and Sweden to cooperate in the accident investigation, however, Chief Executive Ali Abedzadeh has stressed that he would not hand over the aircraft's black box⁠—which may provide details of the doomed flight's final moments⁠—to the United States.

The Iranian government later issued a statement affirming that it would abide by International Civil Aviation Organization regulations and, in addition to inviting foreign representatives to participate in the inquiry, the country would allow Boeing to send a representative to inspect the black box, which Abedzadeh had said was damaged.

Abedzadeh earlier on Thursday dismissed speculation that a missile strike took down Ukraine International Airlines Flight 752. In a statement, he said this outcome was "scientifically impossible and such rumors make no sense at all."

In a rare call Thursday, Canadian Foreign Minister Francois-Philippe Champagne spoke with his Iranian counterpart Mohammad Javad Zarif, to whom he "stressed the need for Canadian officials to be quickly granted access to Iran to provide consular services, help with identification of the deceased and take part in the investigation of the crash."

Champagne said that "Canada and Canadians have many questions which will need to be answered."

Asked whether the Canadian government is considering or leading with the possibility that an anti-aircraft missile took down Ukraine International Airlines Flight 752, Global Affairs spokesperson Krystyna Dodds said her office would have to get back to Newsweek on the matter.

Later Thursday, Canadian Prime Minister Justin Trudeau confirmed that his officials have received "intelligence from multiple sources, including our allies and our own intelligence" indicating "that the plane was shot down by an Iranian surface-to-air missile."

"This may well have been unintentional," he added. "This new information reinforces the need for a thorough investigation into this matter. Canada is working with its allies to ensure that a thorough and credible investigation is conducted to determine the causes of this fatal crash."

The Tor-M1 anti-aircraft defense system is displayed during an annual military parade which marks Iran's eight-year war with Iraq, in the capital Tehran on September 22, 2009.

The Iranian missile strike against Iraqi military positions held by U.S. troops was the latest in a violent series of events involving the two powers. Washington has blamed rocket attacks targeting U.S. personnel on Iraqi militias backed by Tehran and responded with deadly border strikes against these fighters, leading to violent protests at the U.S. embassy, an event followed shortly after by Soleimani's assassination.

The two foes have feuded for four decades but rarely confronted one another directly. The U.S. and Iran's dispute dates back to the 1979 Islamic Revolution that outed a West-backed monarchy and saw diplomats taken hostage at Washington's embassy in Tehran for over 14 months.

Their mutual hostility only worsened as the U.S. backed Iraq's invasion of Iran the following year, a deadly eight-year bout accompanied by so-called "tanker wars" in the Persian Gulf. Shortly before the end of the conflict, a U.S. Navy warship shot down an Iranian passenger plane, Iran Air Flight 655, in 1988, killing all 290 onboard in a missile strike also deemed accidental.

"[The] Pentagon doesn't wish to escalate, especially since we have our own incident from way back," the senior U.S. intelligence official told Newsweek in relation to the 1988 incident that still haunts Tehran and Washington's troubled relations in one of the most important geopolitical flashpoints.

The Persian Gulf is crucial for the global flow of oil. Unrest has now returned to the critical region and its waterways in the wake of Trump's decision to withdraw from a 2015 nuclear deal that granted Iran sanctions relief in exchange for curbing its nuclear activities. The president opted for de-escalation after the recent Iranian missile attack, expanding sanctions but also calling on the Islamic Republic to give up support for militant groups and to stop seeking a nuclear weapon—something Tehran has always denied wanting.
