The government of the Hong Kong Special Administrative Region (HKSAR) condemns violent acts at the Liaison Office of the Central People's Government in the HKSAR on Sunday, a spokesperson of the HKSAR government said.

Some protesters marched to the Liaison Office on Sunday after a public procession finished at around 4.30 p.m., and "maliciously" surrounded and tried to storm the office, some even smeared the Chinese national emblem.

The spokesperson said the HKSAR government will strictly deal with it and investigate in accordance to the law, adding the act was a "public defiance of China's national sovereignty."

"This has posed threats to HKSAR's public security and 'One Country, Two Systems' policy and the Hong Kong society shall not accept it," the spokesperson said in a statement.
