US flies surveillance plane over Korean Peninsula

The US flew another surveillance aircraft over the Korean Peninsula on Monday, an aviation tracker said, the latest in a series of flights to monitor North Korea amid concerns that Pyongyang could launch long-range rockets.

The US Air Force RC-135W Rivet Joint was spotted flying over South Korea at 31,000 feet, Yonhap News Agency quoted Aircraft Spots as saying. Earlier, the tracker said an E-8C, or JSTARS, was spotted flying at 31,000 feet over the peninsula on Sunday.
