North Korea has deployed 250 ballistic missile launchers on its southern borders, as leader Kim Jong Un has described these weapons as a "powerful and precious sword" to protect his country's sovereignty.
The missile launchers were displayed during a "handover" ceremony in the North Korean capital, Pyongyang, on Sunday, North Korean state media reported on August 5.
The missile launchers are "up-to-date tactical attack weapons," Kim was quoted as saying.
This is the first time North Korea has made public the number of weapons transferred across the border, Han Kwon-hee of the Korea Defense Industry Studies Association told AFP.
These types of rocket launchers are designed to carry four missiles, Han said, adding that Pyongyang's arms supply to Moscow "may have interfered with the North's ability to produce 1,000 missiles".
Relations between the two Koreas are at their lowest point in years, as the North has intensified weapons testing and launched balloons filled with debris toward the South.
South Korea has responded by broadcasting propaganda near the border and resuming military exercises near the border.
During this year, Pyongyang has declared Seoul "the main enemy", giving up on reunification and threatening war in case of territorial violation.
Kim acknowledged that the new weapons are being introduced as the country grapples with flood damage. He said that this is a "manifestation of the strong will of our party to continue with the strengthening of defense capacities".
Rains hit North Korea in late July, and South Korean media said up to 1,500 people may have died as a result of the rains.
Kim has dismissed these reports, saying they are intended to tarnish the North's image, while the state has said there have been no casualties as a result of the rains.
During the speech, Kim also said that the country is "facing significant and strategic changes due to the transformation of the Washington-led alliance into a nuclear-based military bloc," adding that this requires his country to strengthen preventive skills.
"The strength of our military must continue to improve," Kim said. REL
