Former Malaysian Prime Minister Mahathir Mohamad has added to this call by asking for an international tribunal to try Western leaders with war crimes over the war in Iraq.
Speaking at Imperial College, London, Mahathir called for a tribunal to try US President George W. Bush and former prime ministers Tony Blair of Britain and John Howard of Australia for their part in the conflict, said a spokesman for the Ramadhan Foundation, which set up the event.
Spokesman Mohammed Shafiq told AFP that Mahathir, who was in office from 1981 to 2003, wants to see the trio tried in absence for war crimes committed in Iraq.
"He said that people have to stop killing each other and use arbitration, negotiation and discussion as an alternative to violence, war and killing."
On the war in Iraq, Mahathir spoke about "the thousands dying, the economic war, the power of oil and how we could utilise some of these tools to have a leverage against the people who commit countries to war," Shafiq said.
More than 450 people attended the speech and about 200 more had to be turned away.
