Hong Kong students armed with bows and arrows and gas pumps hurled police officers throwing tear gas and exploding water cannons as violence escalated paralyzed the educational system of the semi-autonomous Chinese territory under siege.
Late Sunday, police used loudspeakers to order the evacuation of Hong Kong Polytechnic University. Many protesters lagged behind, some igniting to prevent police from advancing.
"Protesters recklessly vandalized facilities and threw bricks and gas stations at police officers, compromising public safety," police said in a statement. Police released an image of what appears to be an arrow stuck in a policeman's leg.
Police said dozens were arrested. The protest was the end of a series of demonstrations that closed several major universities last week.
The Hong Kong Department of Education announced that all schools will close again on Monday "for security" across the territory of 7.4 million people. Kindergarten classes for nearly 1 million students were also canceled on Thursday and Friday due to the impact of the protests on traffic and public transportation.
"All parties must immediately stop all violent and destructive activities in order for students to return to their normal school life," the department said. "If the situation permits, schools could resume classes on Tuesday."
After trying to forcibly evict the protesters, Hong Kong Polytechnic University president Jin-Guang Teng said on Monday that police would allow protesters to leave, and would accompany them to the police station to ensure their cases. " processed fairly. " Protesters may not accept the offer as they will probably all be arrested.
Five university presidents issued a joint statement urging both sides of the conflict to exercise restrictions. Hong Kong Auxiliary Bishop Joseph Ha Chi-shing, who traveled to the school, begged and prayed for a decrease before the violence led to death.
Some universities have reduced their fall semesters. In the US, Georgetown University and Syracuse University announced last week that canceled study programs abroad in Hong Kong for the remainder of the semester due to protests in the region.
A government extradition proposal earlier this year that would allow suspects in Hong Kong to be sent to mainland China sparked months of massive, sometimes violent, protests. The Hong Kong government withdrew the proposal, but protesters seized the moment to press for more freedoms and investigations into police behavior during the protests.
More than 3,000 protesters have been arrested since the protests began five months ago.
Hong Kong was controlled by Britain for over 150 years until 1997, when it ceded control to China. The rich, free-market city has become a special administrative region that has promised a "high degree of autonomy" for 50 years.
Hong Kong's pro-democracy residents have long accused China of slowly invading this autonomy.
Congressional leaders blamed the Chinese government for the unrest and warned Beijing against using force to suppress the protests. President Donald Trump, waged in a trade war with China, has generally avoided criticizing Beijing for its Hong Kong policy. Trump described the situation as "difficult" and "complicated".
