SOUTH KOREA (NEWSCHANNEL 3) - North Korea is apparently making good on some of its recent threats.
Some 10,000 South Korean troops and 3,500 American troops began annual military drills on the border Monday.
After the start of the exercise South Korean officials said their northern counterparts didn't answer two calls on a hotline between the sides, apparently following through on an earlier vow to cut the communication channel.
North Korea has called the exercises provocative and even threatened to launch a nuclear attack on the U.S.
