On 1 May 1988, radical left groups organised a May Day demonstration through Berlin-Kreuzberg, ending in riots even heavier than the year before. The police were attacked with steel balls fired by slingshots, stones, fireworks and Molotov cocktails. On 2 May, headline of the Berlin newspaper BZ was "Beirut?? Nein, das ist Berlin!" (Beirut?? No, it's Berlin!). The riots finally became a tradition in Berlin-Kreuzberg and have recurred every 1 May since, but never as fatally as in the first two years. When the World Bank and the International Monetary Fund met in Berlin in 1988, the autonomen hosted an international gathering of anti-capitalist activists. Numbering around 80,000, the protesters greatly outnumbered the police. Officials tried to maintain control by banning all demonstrations and attacking public assemblies. Nevertheless, there were riots and upmarket shopping areas were destroyed.
