Olmert says certain Iran still seeks nuclear arms

By Jeffrey Heller

BERLIN (Reuters) - Israeli Prime Minister Ehud Olmert said on Tuesday Iran was still seeking to build nuclear weapons and called for a greater international effort to prevent Tehran from succeeding.

"We are certain that the Iranians are engaged in a serious ... clandestine operation to build up a non-conventional capacity," Olmert said at a joint news conference with German Chancellor Angela Merkel after a meeting.

Israel, widely believed to have built hundreds of atomic warheads, has said it considers a nuclear Iran a threat to its existence.

Olmert said he was sharing information with other countries about Iran's nuclear program. He later told journalists he had discussed the issue at length with Merkel during their talks on Monday and Tuesday.

"As (U.S.) President (George W.) Bush once said: no option is ruled out," in dealing with Iran's atomic ambitions, he said, while voicing support for a diplomatic solution.

Bush and Olmert have made clear they still consider Tehran a threat despite a recent U.S. National Intelligence Estimate that said Iran stopped its nuclear weapons program in 2003.

Briefing journalists who traveled with him from Israel to Germany, Olmert declined to estimate when Iran -- which says it is only seeking nuclear energy -- might have an atomic arsenal.

"I have said many times in the past ... and the latest intelligence reports bear this out, that Iran is not as close as it contends to achieving a non-conventional weapons capability but it is not as far from it as we would like," Olmert said.
