The United Nations special envoy to Burma, Razali Ismail, has arrived in Rangoon in a bid to obtain the release of pro-democracy leader Aung San Suu Kyi, detained a week ago. VOA?s Scott Bobb reports the visit comes amid sharp international criticism of Burma's military government.

Mr. Razali arrived in Rangoon Friday saying he hopes to visit Aung San Suu Kyi who has been detained incommunicado for one week. The Malaysian diplomat told Reuters news agency, concern is increasing because nobody has seen her.

"Well, I have heard that she's been injured, some glass pieces have hit her head and there's something wrong with her shoulders but these are all just rumors."

The Burmese military government arrested Aung San Suu Kyi and top leaders of her National League for Democracy party after a clash in Northern Burma. It then sealed party offices and closed Burmese universities.

The government says 4 people died and more than 50 were wounded in the clash, which it blames on the N.L.D. However, the U.S. State Department says its diplomats visited the scene and found evidence the clash was an ambush by what it calls pro-government thugs. It adds that casualty figures could be higher than those of the Burmese government.
