Officials in Burma's Home Ministry say the government has added another year to the house arrest of a senior aide to pro-democracy activist Aung San Suu Kyi.
Tin Oo was taken into custody, along with Aung San Suu Kyi, in May of 2003 after a pro-military crowd attacked their convoy during a political tour of northern Burma.
Aung San Suu Kyi's house arrest was extended by six months last November.
Burma's opposition party, led by Aung San Suu Kyi, has submitted an appeal to the military government challenging her house arrest.
As head of the National League for Democracy, she has spent 10 of the last 16 years in detention, mostly under house arrest.
Both the United States and the European Union have imposed sanctions on Burma for its suppression of the pro-democracy movement.
