Beijing: A major Tibetan monastery has been sealed off by armed troops following an increase in security after celebrations last week over a US award for the region's exiled spiritual leader, the Dalai Lama, an activist group said today.

The Drepung monastery in Lhasa is still surrounded by armed troops, according to the International Campaign for Tibet, a Washington-based pro-Tibet human rights group, citing local sources and several reports.

Hundreds of monks may still be inside the monastery while others may have been detained or injured, it said. Another major monastery in the capital is also closed, the group said.

The awarding of the US Congress highest civilian honour - bestowed by President George W. Bush today - to the Dalai Lama was a setback to Beijing's efforts to undermine support for the spiritual leader, who they regard as a threat to the unity of China and their continued rule over the region.

He remains popular among Tibetans since fleeing into exile 48 years ago after a failed uprising, and has increased his international standing recently by meeting with world leaders.

The International Campaign for Tibet said in a statement that security on roads in and out of Lhasa had been stepped up and residents had been ordered not to carry out religious activities or further celebrations.

Several Tibetans were also temporarily detained after celebrations in a monastery in Gansu province, the group said. Citing eyewitness reports, it said there may have been injuries during clashes with police.
