South Korean and U.S. Marines aim their machine gunds during the U.S.-South Korea joint landing exercises called Ssangyong, part of the Foal Eagle military exercises, in Pohang, South Korea, Monday, March 31, 2014. South Korea says North Korea has announced plans to conduct live-fire drills near the rivals' disputed western sea boundary. The planned drills Monday come after an increase in threatening rhetoric from Pyongyang and a series of rocket and ballistic missile launches in an apparent protest against the annual military exercises by Seoul and Washington.
