Fierce clashes broke out between protesters and riot police in Hong Kong yesterday as thousands marched through the strife-torn city, during a day of global protests aimed at casting a shadow over communist China’s upcoming 70th birthday.  
Beijing is preparing for huge, tightly-choreographed festivities from tomorrow to mark the founding of the People’s Republic of China, including a massive military parade that will revel in the country’s emergence as a global superpower.
 But ongoing unrest in Hong Kong threatens to upstage those celebrations as the semi-autonomous city boils with public anger over the erosion of its special freedoms under Beijing’s rule. Democracy activists in the financial hub had vowed to ramp up their nearly four-month-long campaign ahead of National Day celebrations, which Hong Kong protesters have dubbed a “Day of Grief”.
 Yesterday witnessed the most intense clashes in weeks as police used tear gas, rubber bullets and water cannons at multiple locations for hours during running battles with hardcore protesters hurling rocks and petrol bombs. Using online forums and social media, demonstrators had called for “anti-totalitarian” rallies to be held around the globe. Marches were held in Australia and Taiwan, with more planned in some 40 locations across Europe and North America later in the day. Clashes broke out before Hong Kong’s unsanctioned march had begun after angry groups in the shopping district of Causeway Bay surrounded and heckled officers who were conducting stop and searches.
 But the tear gas fired by police only emboldened the crowds, who then began walking through the streets in their thousands. Some hardcore activists vandalised subway stations, tore down banners proclaiming the upcoming 70th anniversary celebrations and set fire to makeshift barricades. Police spent hours firing tear gas and rubber bullets at different locations across the city centre and were seen making multiple arrests throughout the day.
 An AFP reporter witnessed masked men repeatedly beating pro-democracy protesters in Wanchai district using long sticks. It was not clear if the men were officers dressed as protesters, a tactic increasingly used by the force. A member of the media was also treated by volunteer medics after being hit in the face with a police projectile, while at least two men were attacked by democracy demonstrators and a taxi was trashed.
