Hong Kong prepares for another weekend of protests

PATRICK HAMILTON / AFP

Security forces in Hong Kong are bracing for another potentially violent weekend.

It comes as more anti-government protests planned across the city on Saturday

That includes one at the international airport for a second straight day.

The unrest has caused serious challenge to the central government in Beijing.

Protests in the Asian financial hub began in June against a bill that would allow people to be extradited to stand trial in mainland China.

Since then they've become increasingly violent.
