By NBC News staff and wire reportsSEOUL -- Isolated North Korea claimed Tuesday that the U.S. mainland is "within the scope" of its missiles, two days after South Korea struck a deal with the United States to extend the range of its ballistic missiles.
North and South Korea have been technically at war since their 1950-53 conflict ended in a truce, not a peace treaty, and regional powers have for years been trying to rein in the North's nuclear weapons program.
Follow @NBCNewsWorld (http://twitter.com/NBCNewsWorld) North Korea is believed to be developing a long-range missile with a range of 4,160 miles or more aimed at hitting the United States, but two recent rocket tests both failed.
Its neighbors fear the North is using rocket launches to perfect technology to build a missile capable of delivering a nuclear warhead to the United States.
