Burma's largest opposition party is marking the 15th anniversary of its landslide election victory, which the military government never recognized.

National League for Democracy party officials invited diplomats and journalists to Friday's commemoration in Rangoon. However, NLD leader Aung San Suu Kyi is not able to attend the ceremony. The Nobel Laureate has been under house arrest for two years following a violent ambush by a pro-junta mob.

Her party won 392 of 485 seats in the 1990 election. But the military junta refused to recognize the balloting, which was widely seen as free and fair. The government instead clamped down on opposition parties and began jailing opposition leaders.

On Wednesday, the human rights group Amnesty International slammed Burma's human rights record, saying more than 1,300 political prisoners were wrongly detained last year.
