In the same circumstances, Iran sent 200 tons of medicine to Iraq.
The Islamic Republic lied.
Medicine and food are not under US sanctions. This is the oppression of the Islamic Republic's mafia to the Iranian people.
The Iranian government can communicate anywhere ... sell something or buy something.
I live in Iran, and I see that the Islamic Republic's mafia instead of buying medicines and food supplies its capital to suppress people in Iran and promote violence and assassination elsewhere in the world.
They kill the Syrian people, and tell the people of Iran that I am defending you.
They can buy medicines for their people instead of buying weapons.
Surely buying medicine is more convenient. But the Islamic Republic's mafia is just thinking of itself.
