Hans Blix reflects on Iraq war 10 years on

The UN's former chief weapons inspector, Hans Blix, has spoken about the "tragic and terrible" decision to start the Iraq war.

Mr Blix was speaking to Newsnight's Kirsty Wark as part of a special programme marking the upcoming 10th anniversary of the US-led invasion of Iraq.

The invasion of Iraq led by US troops, in coalition with the UK and other nations, began on 20 March 2003.

The UK lost 179 servicemen and women, of which 136 were killed in action, before the last British troops were withdrawn in April 2009.

The exact number of Iraqis killed in the invasion and ensuing sectarian violence is unknown however, conservative estimates put the figure at around 100,000 dead.
