Hong Kong Chief Executive Carrie Lam Cheng Yuet-ngor sternly denounced on Monday what she called the unprecedented violence in the city on Sunday, saying violence will never be a solution but will only breed more violence.

Lam was condemning the violence during the siege of the Liaison Office of the Central People's Government in the HKSAR in Sai Wan, Hong Kong Island－Beijing's top representative authority in the city－and the attacks in Yuen Long in the New Territories on Sunday night.

Lam and all principal officials of the Hong Kong Special Administrative Region government and the commissioner of police met with the media on Monday afternoon.

She said such violent acts are vicious and have caused citywide indignation. She also promised punishment for anyone involved in such acts.

A peaceful protest against the now-suspended extradition amendment bill on Sunday afternoon turned ugly at night as radical protesters besieged the Liaison Office.
