Iran's Revolutionary Guard has acknowledged that it accidentally shot down the Ukrainian aircraft.

Tensions in the Gulf have risen following the US killing of Iranian military commander General Qassem Soleimani and a retaliatory missile attack by Iran on USA forces in Iraq.
The development of the Chabahar port, however, has been delayed due to tensions between the USA and Iran.
Zarif elaborated on the recent developments in Iran and its extended neighbourhood following Quds Force chief Major General Qasem Soleimani's assassination by the U.S., and said it reflected a very serious problem in America's thinking on the region. The attack, which was blasted by Tehran as an act of terror, prompted Iran to retaliate a few days later by launching dozens of missiles at military bases housing USA troops in Iraq.
