Kim Jong Un vows to speed up nuclear weapons production

North Korean leader Kim Jong Un has vowed to speed up his country's nuclear weapons programme development.

The North Korean leader said this at a military parade this week, according to state media on Tuesday.

Nuclear capabilities must be boosted at the fastest pace; Kim was reported as saying by state-controlled KCNA on Tuesday.

This is according to South Korea's Yonhap news agency.

Kim delivered the speech at a military parade in central Pyongyang celebrating the 90th founding anniversary of the Korean People's Revolutionary Army, Yonhap reported.

The event was late on Monday.

Strategic weapons including a "Hwasong-17'', a new type of intercontinental ballistic missile, were reportedly part of the parade, was a demonstration of the country's military strength.

Previous parades staged to celebrate public holidays had been used to show off new military hardware, including ballistic missiles.

North Korea tested a suspected intercontinental missile in late March in defiance of UN resolutions that banned the testing of nuclear-capable missiles of any range.

The country was subjected to strict sanctions on account of its nuclear weapons programme.
