After weekend of violent clashes, Beijing to address Hong Kong unrest

Police officers line up during a protest against what the activists see as excessive police force against protesters during previous demonstrations, near China's Liaison Office, Hong Kong, China.

Hong Kong bore the scars on Monday of another night of violent protests, with hard hats, umbrellas and water bottles littering some central streets, as Beijing was set to make an announcement on the Asian financial center’s worst crisis since 1997.

In a rare move, the Hong Kong and Macau Affairs Office in Beijing, which has cabinet-level authority over the former British colony, is due to hold a news conference at 0700 GMT about the unrest gripping the city.
