HONG KONG (NYTIMES) - Pro-democracy activists in Hong Kong have called for a strike on Monday (Nov 11), seeking to disrupt the Asian financial centre in the aftermath of the death of a student following a clash with police and the arrest of six pro-democracy lawmakers.

The organisers plan to start disrupting traffic at 7am, but they have kept their specific plans under wraps and were conducting an online poll on Sunday to determine pressure points.

Similar actions in the past have shut down parts of the transit system and the tunnels going to Hong Kong Island that are vital lifelines to its central business district.

The planned disruptions are timed to coincide with "Singles' Day", which gets its name from the date, Nov 11. Originally an anti-Valentine's Day celebration in mainland China, it has turned into an annual shopping phenomenon that generates billions of dollars in sales. The protesters are urging a boycott of online shopping.

The call to action follows a weekend of protests. Last Saturday evening, tens of thousands of people held a vigil to remember Chow Tsz Lok, who died several days after falling from a parking garage near where police officers had clashed with protesters. Sporadic outbreaks of violence also erupted on Saturday and Sunday.

The protests in the semi-autonomous Chinese city began in early June, over a contentious extradition Bill that has since been withdrawn. The demonstrations have since morphed into calls for greater democracy and police accountability.
