IRAN  - The Turkish prime minister says a possible Israeli military strike against Iranian nuclear facilities would lead to an all-out war which will destroy the entire Middle East region.

Speaking to reporters on his return from a two-day visit to Tehran, Recep Tayyip Erdogan said an Israeli attack on Iran's nuclear facilities will have "disastrous" outcomes, adding, "The entire region would be devastated if Israel strikes Iran."

The Turkish premier further stated that a regional war triggered by such an attack "would not end up like the war between the US and Iraq. Israel should not attack Iran."

Erdogan said he shared his concerns regarding the consequences of an Israeli attack on Iran with US President Barack Obama, Today's Zaman reported.

He also criticized the international community for keeping mum on Israel's alleged nuclear weapons, while threatening Iran over its peaceful nuclear energy program.

"Israel has between 250 and 300 nuclear warheads. Nobody is discussing that.... Iran says they would not produce nuclear weapons. They are saying that they would produce a specific amount of enriched uranium rods and stop after that," Erdogan said.

The Turkish prime minister arrived in Tehran for an official two-day visit on Wednesday morning heading a high-ranking politico-economic delegation.

During his meeting with Iran's President Mahmoud Ahmadinejad, Erdogan voiced his country's unwavering support for Iran's nuclear energy program.

"The government and nation of Turkey has always clearly supported the nuclear positions of the Islamic Republic of Iran, and will continue to firmly follow the same policy in the future," he said.

The US and Israel accuse Iran of seeking a nuclear weapons program. However, Tehran refutes their claim as baseless, arguing that as a member of International Atomic Energy Agency (IAEA) and signatory to Non-Proliferation Treaty, it has every right to the peaceful applications of nuclear technology.

Iranian officials have vowed a crushing response to any act of aggression against the country.
