Hong Kong begins national security trial of Tiananmen vigil organizers

Hong Kong has started a national security trial for three pro-democracy activists. They are accused of being organizers of the annual Tiananmen Square vigil, which commemorates the 1989 crackdown in Beijing.

The trial is one of the first major cases brought under Hong Kong's national security law, which was imposed by China in 2020. The law criminalizes acts of secession, subversion, terrorism, and collusion with foreign forces.
