Iran came out strongly in response to a report on Sunday that Israel planned to attack Teheran's nuclear sites, declaring that any attack would be met with a response and that "anyone who attacks will regret their actions very quickly."

According to Iranian Foreign Ministry spokesman Muhammad Ali Husseini, the report published in the London-based Sunday Times proved that Israel was in possession of nuclear weapons

"This step even comes after the Israeli prime minister's admission revealing the fact that the Israeli regime has nuclear weapons in its possession," Husseini said, referring to Prime Minister Ehud Olmert's slip-up last month, when he hinted on German television that Israel was among the world's nuclear-equipped nations.

"Now this will convince the international community that the main threat to the world, and to our region in particular, is the Zionist regime," Husseini said.
