Jailed Hong Kong media mogul Jimmy Lai was among three democracy campaigners convicted on Thursday for taking part in a banned Tiananmen vigil as the prosecution of multiple activists came to a conclusion. Alexandra Wong, 65, was detained on Sunday on suspicion of taking part in an unlawful assembly as she walked towards Beijing's Liaison Office in Hong Kong. Wong -- known locally as "Grandma Wong" -- was a regular fixture of the huge democracy protests that swept Hong Kong in 2019. IMAGES
