Tens of thousands of workers marched in cities from Hong Kong to Istanbul Saturday to mark international worker's day, demanding more jobs, better work conditions and higher wages. More than 100,000 jubilant workers gathered in Istanbul's Taksim Square in the first celebrations at the site since dozens of people died there in a May 1 gathering more than three decades ago. The demonstrations in Istanbul, which sits on both European and Asian continents, marked a special victory for the Turkish unions, which had been denied access to the Taksim Square since 1977, when 34 people died after shooting triggered a stampede. The culprits were never found and workers on Saturday demanded an inquiry into the deaths of the demonstrators. Most of the annual May Day marches were peaceful, but in the Chinese territory of Macau police used water cannons and pepper spray against rowdy protesters who tried to break away from the approved route. Hong Kong radio RTHK reported at least eight people injured. German police also braced Saturday for clashes in the nation's capital where extremists from the left- and right-wing fringes planned May Day marches that have ended in past years with violence, injuries and arrests. Police in Hamburg said 17 officers were injured following clashes on the eve of May 1 with demonstrators who threw paving stones and set garbage cans ablaze in the northern port city. In Indonesia's capital, thousands of workers marched on the presidential palace, shouting: “Workers unite! No more layoffs!”. Rally organizer Bayu Ajie said a free trade agreement with China had cost jobs, decreased wages and encouraged corruption. President Susilo Bambang Yudhoyono promised to create safer working conditions and improve job prospects if the workers maintained political and economic stability. In Seoul, South Korea, Tokyo and Taiwan, thousands marched for better working conditions and permanent jobs. Jeong Ho-hee, spokesman of the Korean Confederation of Trade Union, vowed to fight against long working hours and high death rate related to industrial accidents. In the Malaysian capital, Kuala Lumpur, several hundred workers protested a proposed 4 percent goods and services tax while about 1,000 protesters, including janitors, construction workers and bus drivers, demanded the government in Hong Kong to introduce a minimum wage of 33 Hong Kong dollars ($4.30).
