Following the Indian Ocean tsunami of December 2004, allegations have emerged that after the outbreak of the Somali Civil War in late 1991, Somalia's long, remote shoreline was used as a dump site for the disposal of toxic waste. The huge waves which battered northern Somalia after the tsunami are believed to have stirred up tonnes of nuclear and toxic waste that was illegally dumped in Somali waters by several European firms – front companies created by the Italian mafia. The European Green Party followed up these revelations by presenting before the press and the European Parliament in Strasbourg copies of contracts signed by two European companies—the Italian Swiss firm, Achair Partners, and an Italian waste broker, Progresso—and representatives of the warlords then in power, to accept 10 million tonnes of toxic waste in exchange for $80 million (then about £60 million). According to a report by the United Nations Environment Programme (UNEP) assessment mission, there are far higher than normal cases of respiratory infections, mouth ulcers and bleeding, abdominal hemorrhages and unusual skin infections among many inhabitants of the areas around the northeastern towns of Hobbio and Benadir on the Indian Ocean coast. UNEP continues that the current situation along the Somali coastline poses a very serious environmental hazard not only in Somalia but also in the eastern Africa sub-region.
