North Korea Announces Creation of Nuclear Warheads’ Heatproof Casing

TOKYO (Sputnik) — North Korea successfully conducted ground testing of the heat resistant casing for the nuclear warheads, that would enable reentry of its ballistic missiles into the atmosphere, the national Rodong Sinmun newspaper reported Tuesday.

According to the state-run media, the testing was conducted under the personal supervision of the country's leader Kim Jong-un.

In recent months, Pyongyang has conducted a series of long-range rocket tests, and a nuclear weapons test in early January. In the past week, tensions on the Korean Peninsula have increased with US and South Korean military drills, and North Korea firing a number of short and medium-range rockets towards the Sea of Japan, as well as threatening to continue nuclear tests.

On March 2, the UNSC adopted the resolution which aimed to affect multiple sectors of North Korea's economy, make all cargo going to and from the country subject to inspection and limit or prohibit the nation's export of coal, iron, gold, titanium and rare natural minerals. The resolution also bans conventional arms sale as well as delivery of aviation and rocket fuel to Pyongyang.
