In Hong Kong, anti-government protests show no sign of letting up. Tens of thousands of people took to the streets for a seventh weekend in a row. The protests continued after nightfall, with scuffles breaking out when some protesters defied police orders and marched beyond the official finish point. The rallies were initially sparked by a controversial extradition bill. Though the bill has now been suspended, the protesters are worried about an erosion of freedoms under Chinese rule and under pro-Beijing chief executive Carrie Lam and want free elections. Could Beijing send troops to Hong Kong to quell the protests?
