The Hong Kong government has marked the 22nd anniversary of the former British colony's return to China, as police faced off with protesters outside the venue.
A flag-raising ceremony was held under high security Monday morning with police using riot shields to push back demonstrators who had blocked a nearby street.
Hong Kong leaders and guests watched the ceremony inside the city's convention center instead of outside as they normally do. The government cited inclement weather after light rain earlier in the morning.
A march planned for Monday afternoon is expected to be larger than usual because of widespread opposition to recent government actions that have awakened broader fears that China is eroding Hong Kong's freedoms.
