GUANGZHOU, Sept.12 (Xinhua) -- Sirens are commonplace but military model planes will feature for the first time in an air raid drill scheduled to be held in Guangzhou, capital of south China's Guangdong Province, on Saturday.

    The drill is part of the activities organized to commemorate the 75th anniversary of the Mukden (present-day Shenyang) Incident which occurred on Sept. 18, 1931, when Japanese troops began occupying northeast China. Sept. 18 has been chosen as the day to remind the Chinese people of the national humiliation.

    A circular issued by the people's air defence department of Guangzhou City Government says sirens will wail three times between 3:40 p.m. and 4:40 p.m. in eight urban districts and two county-level cities administered by Guangzhou.

    A simulated attack will be conducted in which military model planes will drop bombs over strategic targets in Guangzhou, while paramilitary artillery forces on the ground fight back, says the circular.

    The drill, the seventh of its kind, will be the largest ever held. More than 1,300 professional air defense personnel will take part in various activities such as emergency evacuation and firefighting, alongside 20,000 civilians including students, civil servants and residents.

    To make sure that people in Guangzhou are not frightened by the sirens and the tumult, the people's air defence department of Guangzhou City Government says they will inform the public about the drill via radio, TV and text messaging. Enditem
