Protesters hurled a Chinese national flag into Victoria Harbor Saturday as a part of ongoing pro-democracy demonstrations in Hong Kong, where the government is bracing for an anticipated general strike set for Monday.

Tens of thousands of supporters blocked roads and surrounded police stations — setting fire to the entrance of one station — as part of growing anger over a bill that would permit extraditions to the mainland.

Violent protests have engulfed Hong Kong for weeks.

The Chinese army this week released a video that depicted soldiers practicing shooting at protesters.
