HONG KONG—Nine people, including six secondary school students, were arrested in Hong Kong on July 6 for allegedly plotting to set off homemade bombs in courts, tunnels, and trash cans as political tensions rise in the city where China is tightening its grip.
Police said the nine were detained on suspicion of engaging in terrorist activity under a harsh national security law that Beijing imposed a year ago to suppress dissent in the former British colony that has long enjoyed freedoms not seen on the Chinese mainland.
