Volodymyr Zelensky, the Ukrainian president,  on Thursday extended his condolences to Afghan President Ashraf Ghani in phone call concerning the death of 10 Afghan citizens in a plane crash in Iran, the Presidential Palace said in a statement.

A Ukrainian airliner carrying at least 170 passengers crashed on Wednesday due to technical problems soon after taking off from Tehran’s Imam Khomeini airport, and all aboard were killed, Iran’s state television said last day.

Zelensky said he ordered a delegation to Iran to investigate the crash.

Zelensky also shared his condolences with the victims’ families.

In return, Ghani also extended his condolences to the president and to victims’ families from Ukraine.

Ghani hoped that Iran will cooperate with the investigative team.
