Vietnam has detained two prominent pro-democracy activists who appeared outside a courthouse in support of another dissident who was being tried.
Foreign Ministry spokeswoman Nguyen Phuong Nga told a regular briefing Thursday that Pham Hong Son and Le Quoc Quan were detained for causing public disorder.
She did not provide additional details.
Son's wife, Vu Thu Ha, told U.S.-funded Radio Free Asia on Wednesday that police hit her husband with batons and arrested him when he appeared Monday outside the court in Hanoi where dissident Cu Huy Ha Vu was being tried.
She said Son, a medical doctor, was taken to a police station along with Quan, a lawyer, and several others.
