Photos show Hong Kong marking the Tiananmen Square crackdown anniversary before and after China imposed a security law which censored protests

• Hong Kong police have stamped out vigils to mark the anniversary of the Tiananmen Square crackdown.
• Photos show how Victoria Park, where demonstrators have gathered for years, has been closed down.
• A new national security law is suppressing the pro-democracy movement in Hong Kong.

Hong Kong blocked demonstrators from entering a park on Friday where thousands of people annually gather to commemorate China's 1989 Tiananmen crackdown.

The gathering in Victoria Park has been held annually since 1990 to remember the 1989 crackdown in Beijing's Tiananmen Square, where pro-democracy protesters were killed by Chinese troops.

Last year's demonstration was canceled due to the COVID-19 pandemic, but photos show a stark difference between Friday's empty park and 2019's vigil.

This year's vigil was the first to be held since Beijing enacted a contentious national security law for Hong Kong that has been used to censor pro-democracy activity. Hong Kong police have arrested pro-democracy activists and are targeting peaceful protests, according to The New York Times.
