Iran's foreign minister defended Tuesday what he said was a "balanced" nuclear deal with world powers, telling lawmakers there was a need to accept that the negotiations had required compromise.

North Korea said Tuesday it had no interest whatsoever in following Iran down the path of nuclear dialogue, insisting it was already a nuclear weapons state and therefore beyond any logical comparison with Tehran.

Iran said its ballistic missile program was not connected to the U.N. Security Council resolution adopted Monday that endorses its July 14 nuclear accord with world powers.

Germany believes Iran should rethink its stance on Israel as last week's nuclear deal means it must "bear new responsibilities, at home and abroad", a top German official said Monday.

British foreign secretary Philip Hammond, who helped negotiate the Iran nuclear deal, said Monday he hoped it would encourage Tehran to play a more constructive role in the region.

"We hope to see an Iran less negative (and which) starts to behave as a more constructive power in the region," Hammond said as he arrived for an EU foreign ministers meeting where the nuclear accord tops the agenda for discussion.

The Iran nuclear deal does not mean military action is off the table when it comes to stopping Tehran from obtaining an atomic bomb, U.S. Defense Secretary Ashton Carter said Sunday ahead of a visit to Israel.

"One of the reasons why this deal is a good one is that it does nothing to prevent the military option," Carter told reporters on board his flight to the Jewish state, the first stop on a Middle East charm offensive to ease concerns among US allies over the landmark accord.

The U.N. Security Council on Monday unanimously adopted a resolution endorsing the historic deal on Iran's nuclear program and cleared a path to lift sanctions crippling its economy.
