Four times as many US troops as originally planned are to take part in a joint military exercise with South Korea next month following nuclear and missile tests by the North, Seoul said Thursday,according to AFP.
The US will send 15,000 troops to the annual computer-simulated "Key Resolve" exercise, the Yonhap news agency quoted Defence Minister Han Min-Goo as saying, up from 3,700 last year.
South Korea would also increase the number of troops it sends, he said.
