About 600 people were killed or injured by an earthquake that shook a remote mountain jungle region of southern China, the state-run China International Broadcasting Station said Monday. The station said it did not have a breakdown on how many of the 600 were dead and how many injured in Sunday's quake. The radio report could not immediately be confirmed independently. Telephone service was cut off to the affected region, in Yunnan province near the Burmese border. The quake measured 7.6 on the Richter scale and was followed overnight and early Monday by 34 aftershocks, the strongest measuring 7.2 on the Richter scale.
