SEOUL, South Korea (AP) — North Korea warned Tuesday the U.S. mainland is within range of its missiles, and said Washington’s recent agreement to let Seoul possess missiles capable of hitting all of the North shows the allies are plotting to invade the country.

South Korea announced Sunday its deal with Washington allowing it to nearly triple the range of its missiles to better cope with North Korean threats. North Korea called the deal a “product of another conspiracy of the master and the stooge.”
