Tony Blair and George W Bush should be taken to the International Criminal Court in The Hague over the Iraq war, Archbishop Desmond Tutu has said.
Writing in the UK’s Observer newspaper, he accused the former leaders of lying about weapons of mass destruction.
The Iraq military campaign had made the world more unstable “than any other conflict in history”, he said.
Mr Blair responded by saying “this is the same argument we have had many times with nothing new to say”.
Earlier this week, Archbishop Tutu, a veteran peace campaigner who won the Nobel Peace Prize in 1984 in recognition of his campaign against apartheid, pulled out of a leadership summit in Johannesburg because he refused to share a platform with Mr Blair.
The former Archbishop of Cape Town said the US- and UK-led action launched against Saddam’s regime in 2003 had brought about conditions for the civil war in Syria and a possible Middle East conflict involving Iran.
“The then leaders of the United States [Mr Bush] and Great Britain [Mr Blair] fabricated the grounds to behave like playground bullies and drive us further apart. They have driven us to the edge of a precipice where we now stand – with the spectre of Syria and Iran before us,” he said.
