Russia of course, was the site of the worst radiation leak disaster at its Chernobyl plant near Kiev in the 1980s. The formerly communist country offered its assistance and expertise to North Korea quickly after the Yongbyon incident occurred on Feb. 25.
The U.S. confirms that 10 EPA agents have been sent to South Korea, where they are monitoring radiation levels and keeping the U.S. abreast of any changes on the ground. The U.S. used its primarily domestic environmental agency in a similar way during the Chernobyl crisis in 1986 in Russia.
North Korea did not supply any estimates of the amount of damage or of injuries.
