In a Sunday interview on CNN, former Iraqi Prime Minister Ayad Allawi denounced Iran as trying to destabilize the Middle East.
"We know that unfortunately Iran is trying to wreak havoc on the region, and trying to destabilize the region by destabilizing Iraq, and destabilizing Lebanon and destabilizing the Palestinian issue," Allawi said.
The Middle East is "falling victim" to terror groups which are supported by Iran, he added.
"I don't believe that there are leaders in the region who are trying to fuel extremism and bring about sectarianism. Unfortunately, only Iran," said the former prime minister.
