Avigdor Lieberman, Israel's foreign minister and deputy prime minister, on Wednesday slammed the nuclear activities of North Korea and Iran as the biggest threat to the international community, but he avoided answering questions about his own country's nuclear development.

Lieberman, in Tokyo for talks with Prime Minister Yukio Hatoyama and Foreign Minister Katsuya Okada, said during a news conference that Japan and Israel are facing similar political issues, including territorial disputes and nuclear threats from neighboring countries.

"The biggest threat for both countries (is) from very radical regimes with nuclear capabilities or the desire to develop nuclear capabilities and missiles," said Lieberman. "This axis of evil that includes North Korea and Syria and Iran is the biggest threat to the entire world."
