Burma's national police chief says 15 dissidents have been arrested in
connection with a plot to plant bombs during the visit of U.N.
Secretary-General Ban Ki-moon last month.
At a news conference Friday, Burma Police Chief Khin Yi linked the bomb plotters to a number of dissident organizations, including the party of detained opposition leader Aung San Suu Kyi. A lawyer for the opposition leader denied that charge.
Khin Yi also said at least 20 security personnel have been demoted - and some jailed - for allowing an American to enter Aung San Suu Kyi's home earlier this year.
John Yettaw swam uninvited to the opposition leader's lakeside Rangoon home in early May, and stayed there for two days with her permission. The incident led to Aung San Suu Kyi's arrest on charges of violating the terms of her house arrest.
The opposition leader has spent the last two months at Rangoon's Insein prison where she was put on trial. The court is expected to hand down its verdict on August 11.
The 64-year-old Nobel Peace laureate, who has spent 14 of the last 19 years in some form of detention, faces up to five years in prison.
Sources say Yettaw was admitted to Rangoon General Hospital Monday after suffering seizures. His condition is said to be improving. Yettaw is reported to have diabetes and other illnesses.
Yettaw, along with two of Aung San Suu Kyi's live-in companions, is also being tried in the case. He testified he swam to her home to warn her of a vision he had that she would be assassinated.
