Hong Kong protesters take cover during an onslaught of rubber bullets

Hong Kong demonstrators nervously take cover as riot police unleashed a volley of rubber bullets and tear gas in another weekend of protests.

Video appears to show a petrol bomb-type device being thrown at a barrier outside Tsim Sha Tsui police station on Sunday (August 11).

Filmer and local photographer Dave Coulson said: "During an anti-extradition bill protest, police fired constant rounds of tear gas, rubber bullets and baton rounds. Protesters can be seen taking cover as someone appeared to throw a Molotov cocktail/petrol bomb [seen here at 30secs] at a water barrier outside Tsim Sha Tsui police station."
