Israel believes that North Korea has been supplying Syria and Iran with nuclear materials, a Washington defense official told the New York Times. “The Israelis think North Korea is selling to Iran and Syria what little they have left,” he said.

The official added that recent Israeli reconnaissance flights over Syria revealed possible nuclear installations that Israeli officials estimate might have been supplied with material from North Korea.

Meanwhile on Wednesday the Nazareth-based Israeli Arab newspaper The Assennara cited anonymous Israeli sources as saying that Israeli jets "bombed a Syrian-Iranian missile base in northern Syria that was financed by Iran... It appears that the base was completely destroyed."

According to the Times, American officials confirmed Tuesday that Israeli jets launched an airstrike inside Syria. Sources said that Israel struck at least one target in northeastern Syria, but could not provide more details.

The most likely target was, according to some administration officials, weapon caches sent by Iran to Hizbullah through Syria.

North Korea commented on the incident Tuesday, calling it a "dangerous provocation", Chinese News Agency Xinhua reported on Tuesday.

"This is a very dangerous provocation little short of wantonly violating the sovereignty of Syria and seriously harassing the regional peace and security," a North Korean Foreign Ministry spokesman said.

"The Democratic People's Republic of Korea strongly denounces the above-said intrusion and extends full support and solidarity to the Syrian people in their just cause to defend the national security and the regional peace."
