Here’s a report from the only Western journalist reporting from Llassa:

Last night I gazed out over a deserted city. After two days of deadly riots and arson attacks, the people of Lhasa hunkered down before a midnight deadline and a feared military crackdown.

Rubble and burnt-out vehicles littered the streets, but few people dared to set foot in the narrow and winding alleyways, fearful of turning a blind corner and running into an army patrol. Only the occasional gunshot rang out over the city, the whoops and cheers of the rioters silenced. Amid claims that many people have been killed in the most dramatic backlash against Chinese rule for almost 20 years, a showdown looms tonight. The rioters must turn themselves in by midnight or face the consequences.

Doesn’t look good.
