State media say a court in southern Vietnam has sentenced three women for up to four years in prison for spreading anti-state propaganda.

Ngo Thi Minh Uoc, 57, was convicted of holding anti-state banners and the flags of the U.S.-backed South Vietnamese government and chanting anti-state slogans outside the United State diplomatic mission in July 2014, and sentenced to four years in prison at the trial that lasted half a day on Wednesday, Thanh Nien newspaper reported.

Nguyen Thi Tri and Nguyen Thi Be Hai, both 58, were given three years in prison on the same charges, it said.

The sentences came a week after a court in Hanoi sentenced a prominent blogger to five years in prison for posting anti-state writings.
