Ukraine International Airlines flight PS752 to Kyiv went down after taking off from Imam Khomeini airport in Tehran at 06:12 local time (02:42 GMT). The majority of passengers were from Iran and Canada. Ukraine's Tehran embassy initially blamed engine failure but later removed the statement. It said any comment regarding the cause of the accident prior to a commission's inquiry was not official. Ukraine's president, Volodymyr Zelensky, warned against "speculation or unchecked theories regarding the catastrophe" until official reports were ready.
