Hong Kong's pro-democracy student protesters return to streets for biggest rally

Hong Kong's pro-democracy student protesters have returned to the streets for their biggest rally since the mass protests started last year.

According to BBC, the protesters are demanding completely democratic elections for the territory's leader and oppose China's decision to vet candidates.

Tens of thousands of people had attended the Occupy demonstrations last year.

Before the final protest camp was dismantled in December last year, there had been violent clashes between the protesters and the police.
