Washington: The US has imposed sanctions on Iran’s central bank and its national development fund following attacks on Saudi Arabia’s oil facilities a week ago. US President Donald Trump announced the new move at the White House on Friday before a meeting with visiting Australian Prime Minister Scott Morrison, calling the new sanctions on Tehran “the highest sanctions ever imposed on a country”, Xinhua reported. US Treasury Secretary Steven Mnuchin, accompanying Trump in the Oval Office, said the central bank was Tehran’s last source of funds. US Treasury later announced in a statement that it has blacklisted Iran’s central bank and its national development fund, which it claimed have been used to “move Iran’s foreign currency reserves for terrorist proxies”.
