North Korea's media reports that its leader Kim Jong Un has inspected major weapons factories, including those producing shells for large-caliber multiple rocket launchers and mobile missile launchers.

Sunday's edition of the ruling Workers' Party newspaper, Rodong Sinmun, said Kim visited the factories between Thursday and Saturday.

The paper carried photos it said were taken at the mobile launch pad factory. They show transporter erector launchers, which are believed to be used for loading intercontinental ballistic-class missiles.

Kim reportedly noted its increased production capabilities.

The report also said Kim inspected the factory that manufactures engines for strategic cruise missiles and unmanned aerial vehicles.

Kim reportedly called for rapid expansion of its production capacity.

The visits come after a military parade on July 27 marking the 70th anniversary of the Korean War armistice. The parade featured large drones and a new type of solid-fuel ICBM class missile, called Hwasong-18, on a mobile launcher.

The North Korean leader appears to have used the latest inspections to highlight his intention to further enhance the country's defense capabilities, with the United States and South Korea in mind.
