UK's Brown warns of harsher sanctions on Iran

British Prime Minister Gordon Brown warned Thursday that Iran will face harsher sanctions if it moves forward with a nuclear weapons program.
Brown's comments came as hundreds of thousands of Iranians gathered in a central Teheran square to mark the 31st anniversary of the revolution that created the Islamic republic.
Speaking to reporters in Belgium, the UK prime minister said that while he would like to see dialogue with Iran, “the patience of [Western] countries is not inexhaustible”.
“I think the choices could not be clearer. Iran can either pursue a civilian nuclear program, respect human rights and earn the trust and respect of the international community, or it can move ahead with its nuclear weapons program, trample on human rights and be isolated and ostracized on the wrong side of history, outside the international community," he said.
He also noted that the UK was stepping up talks with other countries about tougher sanctions on Iran.
