Pompeo returns to Washington to discuss Iran, North Korea
Pompeo first changed his plans to have meetings on Iran after U.S. President Donald Trump on Wednesday imposed fresh sanctions on Iran over its nuclear programme.
The sanctions target revenue from industrial metal exports in the latest escalation of tensions between Washington and Tehran.
Then, North Korea also joined the agenda, after the South Korean military said North Korea had fired missiles, less than one week after North Korean leader, Kim Jong Un, oversaw the test-firing of rockets and a missile.
Pompeo had been scheduled to visit Greenland, but instead left London for Washington.
The tests by North Korea were its first of a ballistic missile since Pyongyang launched an intercontinental ballistic missile in November 2017.
