In this photo by Vincent Yu, police officers use their batons to try and disperse pro-democracy protesters outside Hong Kong government headquarters early Monday. The protesters were met by police as they tried to surround the building late Sunday, stepping up their movement for genuine democratic reforms. Protesters said they were trying to force a response from Hong Kong's government as they continue to press their demand to scrap a plan requiring a Beijing-friendly panel to screen candidates for the territory's inaugural leadership elections in 2017.
