A prominent Hong Kong activist in exile in the U.S. says a court ruling back in Hong Kong to imprison her father for eight months has only made her more determined to fight for the territory and its people.

A Hong Kong court has sentenced the father of a U.S.-based activist to eight months in prison in the first case brought against the relative of a pro-democracy activist wanted by the city's authorities under a national security law.

Hong Kong’s leader says eight pro-democracy activists who now live in the United States, Britain, Canada and Australia will be pursued for life for alleged national security offenses.
