Iranian President Mahmoud Ahmadinejad on Tuesday questioned the veto right of the UN Security Council's the permanent members, two days before the council's deadline demanding Tehran stop uranium enrichment. "The US and Britain are the source of many tensions. At the Security Council, where they have to protect security, they enjoy the veto right. If anybody confronts them, there is no place to take complaints to," he said during a press conference. Ahmadinejad also called for having a televised debate with US President George W. Bush on world issues. The UN Security Council has given Iran until Thursday to suspend a key part of its nuclear program - the enrichment of uranium, a process that can produce either fuel for a reactor or material for weapons.
