Tens of thousands of masked protesters armed with umbrellas and goggles are occupying all roads leading to Hong Kong's legislature as the government is forced to delay the debate on the highly contentious extradition bill. Protesters, mostly young people who had camped there overnight, are building metal barricades and walls of loose bricks in a face-off with riot police bearing shields and batons. Police fired pepper jets into the crowds earlier. Pro-government lawmakers are nowhere in sight.Today’s protest follows on Sunday’s biggest march since the 1997 handover.
