Spectator Index has reported that a Russian official has said that Iran must learn lessons from its downing of a Ukrainian plane.
The remarks come after the Iranian government has admitted that it shot down the Ukranian plane by mistake killing all the 176 passengers (mostly Iranians and Iranian-Canadians) and crew on board.
Previously, the Iranian government was saying that the plane caught fire before it crashed whilst the USA was saying that the Iranian army might have accidentally shot down the plane.
Ballistic missile experts have been saying that a Russian-made missile brought the plane down.
The developments are taking place when tensions between the USA and Iran are mounting.
