[ti:Iran Denies Shooting Down Ukrainian Plane] [by:www.51星和彩票.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]Iran has denied reports that one of its missiles hit a Ukrainian passenger airplane. [00:09.00]The Ukraine International Airlines jet crashed earlier this week near Tehran, [00:15.88]killing all 176 people on board. [00:21.24]Iranian officials called on the United States and Canada Friday [00:26.72]to share any information they have on the crash. [00:31.76]The plane broke up just hours after Iran launched missiles at two air bases in neighboring Iraq. [00:41.12]The bases housed U.S. troops. [00:44.48]Iran launched the attacks to answer the killing of its top general in a U.S. airstrike last week. [00:54.08]The downed aircraft was carrying 63 Canadians. [00:59.64]On Thursday, Canadian Prime Minister Justin Trudeau said, [01:04.72]"The evidence indicates that the plane was shot down by an Iranian surface-to-air missile." [01:13.08]He noted the information came from several intelligence sources. [01:19.48]U.S. officials said that Iran might have mistakenly identified the Boeing 737 as a threat. [01:29.48]Ali Abedzadeh is head of Iran's national aviation office. [01:35.28]He said Friday, "What we can say with certainty is that no missile hit the plane." [01:43.56]He urged Western nations to, in his words, "come and show their findings to the world." [01:52.08]Western governments may not be ready to share the information [01:57.36]because it comes from highly classified intelligence sources. [02:03.88]However, The Associated Press, The New York Times and other media companies [02:10.64]released videos appearing to show something hitting a plane near Tehran's main airport. [02:19.00]In one video from The Associated Press, someone off camera says: [02:25.00]"The plane has caught fire...In the name of God, the compassionate, the merciful. [02:30.00]God, please help us. Call the fire department!" [02:34.04]The comments were made in Farsi, the official language of Iran. [02:40.04]Shortly after the crash, Iran reported the recovery of the plane's flight recorders -- or black boxes. [02:49.56]Abedzadeh announced, "We prefer to download the black boxes in Iran. [02:55.76]But if we see that we can't do that because the boxes are damaged, then we will seek help." [03:03.76]The head of the Iranian investigation team said that the process could take more than a month [03:11.12]and that the investigation could stretch into next year. [03:15.96]Under United Nations aviation rules, the U.S. National Transportation Safety Board, or NTSB, [03:25.28]can join the investigation because the crash involved an airplane designed and built in the U.S. [03:34.52]The NTSB said Thursday night that its involvement could be limited by U.S. sanctions on Iran. [03:44.08]U.S. officials have expressed concern about sending employees to Iran because of the heightened tensions. [03:54.36]Iran had first said it would not let Boeing -- the plane's manufacturer -- take part in the investigation. [04:03.28]The state-operated IRNA news agency later reported that Iran [04:10.04]"has invited both Ukraine and the Boeing company to participate in the investigations." [04:18.00]In Ukraine, President Volodymyr Zelenskiy said "the missile theory is not ruled out, [04:25.72]but it has not been confirmed yet." [04:29.12]The government said it wanted to search the crash site for any sign of a Russian-made missile used by Iran. [04:39.20]A preliminary Iranian report released Thursday noted that the plane's pilots never made a radio call for help. [04:49.88]The report said that an emergency problem happened just minutes after the flight left Tehran. [04:58.84]The plane reportedly was heading to a nearby airport before it crashed.
