Chinese student leader Wang Dan, who helped lead China's 1989 democracy movement, apologized for his actions before the court that sentenced him to four years in prison, a pro-Beijing Hong Kong newspaper reported Monday.

The Wen Wei Po newspaper said Wang, 23, delivered a 20-minute "self-defense" at the trial in Beijing, which ended Saturday. The trial was closed to foreign journalists.Wang was a key figure in the student-led democracy demonstrations at Beijing's Tiananmen Square that were crushed by troops in June 1989. Hundreds of people were killed.

Four other democracy activists were sentenced, including veteran dissident Ren Wanding, who received a seven-year jail term.
