Myanmar news media in exile say the military junta has launched a series of cyber attacks on dissident websites.
Thousands of monks took to the streets of Yangon in Sept. 2007 to protest against the junta
A Thailand-based weekly journal, the Irrawaddy, has described the online assault, which blocks access for users in Myanmar, as persistent and very sophisticated.
In a posting on a temporary site hosted on a back-up server, it said the crackdown coincided with the anniversary of Buddhist monk protests against the junta that began in Yangon on September 18 last year.
Similar outages were reported at the Burmese-language New Era Journal and the Democratic Voice of Burma, an Oslo-based news outlet that aired footage of the 2007 protests and the ensuing crackdown.
