Iran will “take a strong step” away from its 2015 nuclear deal with world powers if Europe cannot offer the country new terms by a deadline at the end of this week, a government spokesman said.

Donald Trump on Tuesday pulled out of an international nuclear deal with Iran, making investors nervous about rising risks of conflict in the Middle East and about oil supplies in a tight market.

U.S. President Donald Trump said he would announce a decision on the future of the Iran nuclear deal on Tuesday as European countries piled pressure on Washington to remain in the 2015 agreement.
