UK, US issue alert over threats to westerners in Beijing

The UK and US governments have issued a warning about possible threats against Westerners in the Chinese capital on or around Christmas Day.
British and US officials say they have received information of possible threats in Sanlintun, which is a busy bar and shopping district.
The Australian and French governments have also urged their citizens to remain vigilant.
Beijing police have issued a yellow security alert in the city.
A yellow alert is the second lowest level in China's four-level security alert system.
