Prime Minister Hun Sen on Tuesday said that the United Nations and countries that supported Pol Pot at the United Nations from 1979 to 1991 should be tried by the Khmer Rouge tribunal. "[The UN] realised that Pol Pot killed people, but they still supported Pol Pot," Hun Sen said. "Supporters of Pol Pot should be punished more than members of Pol Pot's regime." But the law does not allow trying them because their crimes are too broad, he said. He added that UN delegates who came to Cambodia during early negotiations about the tribunal were the ones who supported Pol Pot.
