US Defense Secretary Jim Mattis is expressing worry about what he calls "reckless" actions by North Korea, alluding to its nuclear weapons and missile programs.
Mattis spoke at a news conference Friday in London with his British counterpart, Michael Fallon.
Mattis raised the North Korea issue in response to a reporter's question about Iran. Mattis suggests that North Korea is a more urgent problem.
North Korea is reportedly preparing a new nuclear test. Mattis says North Korea has "got to be stopped."
