Chief U.N. weapons inspector Hans Blix said yesterday the U.S. case for an invasion of Iraq was built on false intelligence reports, referring to false documents purporting to show that Iraq had imported tons of uranium. He told the BBC it’s disturbing that U.S. and British intelligence agencies did not discover that the documents were falsified, and asked who falsified them. Blix also accused U.S. officials of deliberately seeking to discredit his team in the run-up to the war in a bid to win political support for the invasion. In a briefing to the U.N. Security Council, Blix said that without U.N. verification, U.S. post-invasion inspections lack credibility.
