In Dhaka, Bangladesh, an angry May Day march descended on the city center with drums, red flags, and chants of "Hang the killers, Hang the Factory Owners!" In Jakarta, Indonesia, some of the tens of thousands of marchers were dressed as ants—complete with bright red outfits and antennae—to depict the exploitation of workers. In Hong Kong, the ranks of marchers were swollen past 10,000 by striking dockworkers and their supporters. In Greece, transport came to a halt as thousands of public-sector workers walked off the job in a one-day strike. May Day protests in downtown Seattle turned violent, with police using pepper spray to disperse anarchists who pelted them with rocks, bottles, metal pipes, fireworks and a skateboard. (CSM, CNN, AFP, SCMP, May 1)
