The police force of China's Hong Kong Special Administrative Region (HKSAR) conducted an anti-terror drill at a downtown community Monday morning.
The drill, code-named "Skyvault", involved police hunting a terrorist who blended into a crowd after officers "took down" six others armed with assault rifles and handguns.
The 90-minute drill began with seven terrorists storming Hong Kong City Hall, a complex in Central providing municipal public services, and shooting citizens indiscriminately.
Shortly, police arrived and disposed of four, but three went into a hall during a piano recital. Two more were shot by anti-terrorism squad officers while one got into the crowd.
Amid an evacuation, the police force's Affected Person Processing Unit had to spot the seventh terrorist.
The drill was the first at Hong Kong City Hall but was the 13th such exercise in the SAR so far this year. About 200 officers from the Counter Terrorism Response Unit, the Police Tactical Unit and Hong Kong Island Regional Headquarters together with its emergency unit were deployed.
