LONDON (AP) _ British Prime Minister Gordon Brown said Tuesday that his government will seek further sanctions against Iran through the United Nations and the European Union to discourage Tehran's nuclear ambitions.
"We are absolutely clear that we are ready, and will push for, further sanctions against Iran," Brown said at a joint news conference with Israeli Premier Ehud Olmert.
"We will work through the United Nations to achieve this. We are prepared also to have tougher European sanctions. We want to make it clear that we do not support the nuclear ambitions of that country."
Olmert endorsed that message.
"Economic sanctions are effective. They have an important impact already, but they are not sufficient. So there should be more. Up to where? Up until Iran will stop its nuclear program."
As the two leaders met in London, EU foreign policy chief Javier Solana was to meet in Rome with Saeed Jalili, Iran's newly appointed chief negotiator on the nuclear issue, and his predecessor Ali Larijani.
Brown sidestepped a question about when military action might be necessary.
"I believe sanctions are working. I believe that we should step them up if it becomes necessary, and they will be shown to be working even more successfully.
"I believe the combination of our willingness to go through the UN process, which we will do, and our ability to take sanctions as a European Union, sends the strongest possible message to Iran," Brown said.
"The pressure will be maintained. The pressure in fact will be stepped up."
