North Korea is believed to be preparing to launch another ballistic missile in retaliation for an upcoming joint naval drill by the US and South Korea, it emerged today..

The US Navy said on Friday that the USS Ronald Reagan aircraft carrier will lead the drill in the coming week, as another show of force against dictator Kim Jong-un’s ongoing nuclear and weapons programme.

A riled Pyongyang immediately renewed its threat to fire missiles at the US Pacific territory of Guam, warning that “reckless moves” by the US would compel it to take action.
