Opposition politicians in Burma say the country's military-ruled government has cut off phone service for about 50 politicians and activists in an apparent effort to halt weeks of protests.
National League for Democracy officials said today that mobile phone lines of party members and activists have been cut, as well as a land line to the party's headquarters.
Pro-democracy demonstrators have held a series of marches in Burma for nearly a month to protest a large hike in fuel prices.
The government says the hike was needed because of high world oil prices.
Activists say authorities have arrested at least 100 demonstrators. The government says it is holding 50 people. Earlier in the week, Burma's military government warned that it would take what it calls "effective action" to put an end to weeks of anti-government protests.
