A Ukrainian Boeing-737 carrying 176 people has crashed in Iran and officials say there is no chance of finding survivors.
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. Iranian media blamed technical problems and quoted an aviation official who said no emergency had been declared.
Debris and engine parts from the Boeing 737-800 NG plane were found some 10km (6 miles) from the airport and rescue workers with face masks searched the wreckage for victims.
Who was on board?
Among the victims were 82 Iranians, 63 Canadians, 11 Ukrainians including all nine crew, 10 Swedes, four Afghans, three Britons and three Germans, Ukrainian Foreign Minister Vadym Prystaiko said.
Ukrainian officials said that 169 people had bought tickets for the flight but two had not boarded the plane.
It was unclear why such a large number of Canadians were on board, however the airline provides relatively inexpensive flights via Kyiv to Toronto.
Sweden’s foreign ministry said its embassy in Tehran was seeking further information about the crash. Foreign Minister Ann Linde said she had spoken to Mr Prystaiko.
Iran’s head of emergency operations said 147 of the victims were Iranian. That would suggest that 65 of the foreign nationals had dual nationalities.
