Iraqi Prime Minister Haider al-Abadi has called for on Tuesday during a press conference for a full investigation into the 2003 US-led invasion of Iraq..

He said he wants to see a “thorough investigation” on why the US decided its troops needed to be “occupying” Iraq.

“The US invasion of Iraq removed [former Iraqi dictator] Saddam [Hussein]’s regime, but on the other hand it led to… tragedies,” he pointed out.

This call for an investigation comes just as US President-elect Donald Trump said earlier this week that the war on Iraq was “possibly the worst decision” ever made in American history.
