The US Department of the Treasury has imposed sanctions against Iranian Foreign Minister Mohammad Javad Zarif, BBC News reported.

The sanctions freeze any assets of Zarif in America, or controlled by US entities, the department said.

“Javad Zarif implements the reckless agenda of Iran’s Supreme Leader (Ayatollah Ali Khamenei),” Treasury Secretary Steven Mnuchin said.

Zarif tweeted the US had imposed sanctions on him because it considered him as a threat to its agenda.
