A top official with Burma's government-in-exile says pro-democracy leader Aung San Suu Kyi has been hospitalized with digestive problems.
The U.N. representative for Burma's government-in-exile, Thaung Htun, told the Voice of America-Burmese service from his New York office Friday that the opposition leader called her physician complaining of diarrhea and weakness.
He said colleagues in Burma told him that Aung San Suu Kyi had to delay going to the hospital because her physician had trouble getting permission to see her.
Thaung Htun said he did not know whether she is still at the hospital.
Earlier Friday, the U.S. State Department expressed concern about the reports of her hospitalization, while saying it had been unable to confirm them.
But the State Department spokesman Sean McCormack said the Burmese government should provide Aung San Suu Kyi with any medical assistance she might need.
Also Friday, Burma's military government acknowledged for the first time that Aung San Suu Kyi's house arrest had been extended for one year.
It said the May extension was ordered after the government determined that she remains a threat to the state.
She has been detained or under house arrest for 10 of the past 17 years.
The United States is seeking a U.N. resolution to put pressure on Burma to change its policies.
But Burmese officials say such a resolution is unacceptable because what is happening in their country poses no threat to the international community.
