A pro-democracy protest in Hong Kong was disrupted by pro-Beijing counter-demonstrators waving Chinese flags. The sit-in at a shopping mall in the semi-autonomous Chinese territory became the scene of violent clashes when pro-Beijing activists confronted the demonstrators. Police were said to have arrested some activists from the pro-democracy camp but to have left pro-Beijing protesters alone. Hong Kong is in its fourth month of pro-democracy demonstrations, which were initially launched to oppose a controversial extradition bill, but have since widened to demand free elections.
