HANOI, Vietnam — The mother of a prominent Vietnamese blogger has died after setting herself on fire ahead of her daughter's trial next week.

A police officer in the southern province of Bac Lieu says 64-year-old Dang Thi Kim Lieng died on the way to the hospital after setting herself on fire near the provincial offices Monday morning.

Lawyer Ha Huy Son says Lieng's daughter Ta Phong Tan and two other bloggers are scheduled to be put on trial next week.

The three belong to the outlawed Free Journalists Club. They are accused of posting and writing hundreds of articles on their blogs that distorted and opposed the communist government.
