Britain and other European governments have helped the US commit countless" crimes by colluding with torture and illegal rendition operations in America's war on terror, Europe's human rights watchdog has said. Thomas Hammarberg, the Council of Europe's rights commissioner, accused governments of being "deeply complicit" in illegal activities carried out by the US over the last 10 years, since the September 11 2001 terrorist attacks on New York and Washington. "In attempting to combat crimes attributed to terrorists, countless further crimes have been committed in the course of the US-led 'global war on terror'," he said. "Many of those crimes have been carefully and deliberately covered up." A 2007 Council of Europe (COE) report by Dick Marty, Swiss MP, accused Britain and 13 other European governments of allowing the CIA to run secret detention centres, of turning a blind eye to torture and the illegal abductions of terror suspects. Mr Hammerberg accused Europe's governments of blocking investigations into rendition in line with Washington's wishes. "So far Europe has granted effective impunity to those who committed crimes in implementing the rendition policy. An urgent rethink is required to prevent this misjudged and failed counter terrorism approach from having a sad legacy of injustice," said Mr Hammerberg.
