US sanctions 'possible' on European companies doing business with Iran: Bolton

WASHINGTON: Sanctions on European companies that do business with Iran after the US withdrawal from the nuclear deal are "possible," White House National Security Adviser John Bolton said on Sunday.

"It's possible. It depends on the conduct of other governments," Bolton said on CNN's "State of the Union."

US President Donald Trump's pullout from the 2015 nuclear deal has upset Washington's European allies, cast uncertainty over global oil supplies and raised the risk of conflict in the Middle East.
