The Latest: Iran FM warns US against war with his country

The Latest on tensions between Iran and the U.S. and developments in the Persian Gulf region (all times local):

1:45 p.m.

Iran's foreign minister is warning amid tensions between Washington and Tehran that "whoever starts a war with us will not be the one who finishes it."

Mohammad Javad Zarif made the remarks on Monday, speaking alongside visiting German Foreign Minister Heiko Maas.

Maas is in Tehran in an effort to salvage Iran's 2015 nuclear deal with world powers. Germany is a signatory to the accord.

Zarif came out to a news conference in Tehran grim-faced after a long private discussion with Maas, who on Sunday called Iran's ballistic missile program problematic.

The U.S. pulled out of Iran's nuclear deal over a year ago. That's the root of the current tensions with Iran. In May, Tehran said it would begin enriching uranium closer to weapons grade if Europe didn't come up with new terms for the deal by July 7.

Iran's Foreign Ministry says nothing else but the country's landmark 2015 nuclear deal with world powers will be discussed during high-stakes diplomacy meetings in Tehran this week.

Iranian state television quotes spokesman, Abbas Mousavi, as saying that visiting "European officials are not in a position to comment on Iran's issues beyond the nuclear deal."

The remarks came after German Foreign Minister Heiko Maas called Iran's ballistic missile program problematic during a visit Sunday to the United Arab Emirates.

Maas is now in Iran amid heightened tensions between Washington and Tehran. The tensions recently soared over America deploying an aircraft carrier and B-52 bombers to the Persian Gulf over a still-unexplained threat it perceives from Tehran.

After Maas, Japanese Prime Minister Shinzo Abe will arrive on Wednesday in Iran.
