A South Korean security expert has shared his concerns over North Korea's increasingly 'advanced' missile technology.
Choi Kang, vice president of the South Korean think tank The Asan Institute for Policy Studies, warned that North Korea's military capabilities are developing rapidly.
He commented on the rogue state's 'imaginative or creative thinking' in relation to building weapons, pointing to a lumber truck fitted with missiles as an example.
He added that North Korea has almost perfected the ability to evade missile defence systems, CNN reports.
It comes just weeks after dictator Kim Jong-un fired two unidentified projectiles into the Sea of Japan.
Japan's coastguard said it had detected ballistic missile launches from North Korea on Saturday and warned shipping to stay to stay clear of any debris.
South Korea's Joint Chiefs of Staff (JSC) said the projectiles were fired from around Sondok, the site of a North Korean military airfield.
Leader Kim Jong-un has fired a number of missiles into the sea in recent months amid stalled talks with the US.
Kim has been on a quest to build a warhead small enough to be mounted on a ballistic missile capable of flying across the Pacific and hitting the US mainland.
The dictator has met three times with US President Donald Trump - at summits in Singapore and Vietnam, and at the North Korea-South Korea border after talks stalled.
After the second meeting collapsed without an agreement on denuclearisation or sanctions, North Korea resumed missile tests and has issued threats against the US.
