North Korea says it has conducted a test-firing of its latest anti-aircraft missile system with the country's leader Kim Jong Un overseeing the launch.



State-run Korean Central Television reported on Friday that the Missile Administration conducted the test the previous day. It said the missile system has entered full-scale production.



It said Kim gave a positive assessment of the test results. Kim reportedly said the country's military will be equipped with another major defense weapon system.



A South Korean expert pointed out that North Korea may have received air defense technological and equipment assistance from Russia in return for dispatching troops.



Sources related to the South Korean military said on Friday that North Korea launched several missiles from near Onchon in western North Korea toward the Yellow Sea west of the Korean Peninsula at about 9 a.m. on Thursday.



The South Korean military, in coordination with the United States, is reportedly analyzing the missile types and monitoring North Korea's movements.



Meanwhile, North Korea's defense ministry released a statement carried by the state-run Korean Central News Agency on Friday, criticizing a US-South Korea joint military exercise that simulated an emergency on the Korean Peninsula and concluded the day before.
