A plane carrying UN medical experts and aid touched down Monday in Iran on a mission to help it tackle the world's second-deadliest outbreak of coronavirus as European powers said they would send further help.
As the official death toll rose by 12 to 66, the Islamic republic turned down a similar offer from arch-enemy Washington, dismissing it as "propaganda".
The World Health Organisation said a flight arrived from Dubai carrying medical supplies and experts on a fact-finding mission and to "provide guidance on strengthening and scaling up the response to the ongoing outbreak."
US President Donald Trump had Saturday offered: "If we can help the Iranians with this problem, we are certainly willing to do so... All they have to do is ask."
"What we see now is that demand has greatly exceeded our available stocks... and we are struggling to get access to more supplies."
