The People's Liberation Army yesterday ended a five-day drill to defend Beijing from air attack. More than 12,000 personnel from the land, air and naval forces in Shandong and Henan provinces took part in the drill conducted by the Jinan Military Command, which oversees the defence of the area south of the capital, including the Yellow Sea region. Xinhua said unmanned planes, reconnaissance aircraft and five types of modern fighter jets were deployed while anti-aircraft weapons including the new generation of land-to-air missiles were tested. The drill comes amid rising tension in the South China Sea. Military experts said it was aimed at dealing with a 'decapitation attack', a strategy commonly used by the United States military.
