This news was published in Voice of Tibet, however I question the validity of it. Of all monasteries of the Sakya lineage in the world, why would the Sakya Trizin write to this relatively remote and unknown monastery in Tibet asking them to give up Dorje Shugden? But if the news is true, then maybe this monastery is especially well-known for its Dorje Shugden practice therefore the Sakya Trizin specifically targeted it?
And why would Sakya Trizin out of the blue decided to come down harsh on Dorje Shugden practitioners when everything seemed to quiet down last year?

http://www.vot.org/?p=4516Tibetans vowed not to worship Dorje Shugden[Voice of Tibet, November 28, 2011] Monks and lay people in Tibet's Kham Kyegudo area recently threw Dorje Shugden's statues and books in to the river and vowed not to practice Dorje Shugden anymore.
A monk from India's Sera monastery told the reporter that Gesang Monastery in Tibet's Kyegudo area recently received two letters written by Sakya Trizin personally, the letter listed out in detail high lamas of the Sakya sect who oppose Dorje Shugden, and urge the monks and people of Gesang Monastery to stop propitiating to Dorje Shugden.
In Sakya Trizin's second letter to them, he demanded the monastery to decide immediately and to announce publicly the list of monks who would stop propitiating to Dorje Shugden, so Gesang Monastery held an emergency meeting and asked people to gather all Dorje Shugden items and throw all Dorje Shugden statues, images, books into the river, and vowed not to practice Dorje Shugden anymore.
Gesang Monastery was built in 1260, it used to have over a thousand monks, now it has around 200 monks.
