CURRENT STATUS OF RELIEF AND RESCUE

BRUSSELS, March 5 (Reuters) - NATO allies will keep supporting Ukraine despite the situation in Iran, NATO Secretary General Mark Rutte told Reuters on Thursday.

"Many leaders in Europe and the United States, Canada say it has to be 'and, and': make sure that as allies we enable what the Americans are doing in the Middle East ... and at the same time make sure that Ukraine has what it needs to stay strong in the fight", he said.

BRUSSELS, March 5 (Reuters) - The shooting down of a ballistic missile headed for Turkey by NATO air defences does not provide immediate reason to trigger the alliance's Article 5 mutual defence clause, its Secretary General Mark Rutte told Reuters on Thursday.

"Nobody's talking about Article 5," Rutte said. "The most important thing is that our adversaries have seen yesterday that NATO is so strong and so vigilant, and even more vigilant, if possible, since Saturday."

DUBAI, March 5 (Reuters) - Wealthy Gulf states are facing their biggest food security challenge since the 2008 global food crisis, as the Iran conflict threatens ports and disrupts shipping through the Strait of Hormuz.

The war is testing strategies adopted after 2008, when soaring food prices prompted Gulf nations to shift toward import-dependent policies reliant on pouring cash into agricultural investments abroad.

BRUSSELS, March 5 (Reuters) - Countries in the Middle East have told European officials they are concerned about the risk of civil war in Iran as a result of the conflict between Tehran and the United States and Israel, EU foreign chief Kaja Kallas said on Thursday.

BAKU, March 5 (Reuters) - Azerbaijan's foreign ministry lodged an official protest with the Iranian embassy on Thursday after a pair of Iranian drones flew across the border into Azerbaijan and injured two people at an airport in the Nakhchivan exclave.

"This attack on the territory of Azerbaijan contradicts the norms and principles of international law and contributes to increased tensions in the region," the foreign ministry said in a statement.

MOSCOW, March 5 (Reuters) - Iran has not approached Moscow with a request for arms supplies, the Kremlin said on Thursday.

Russia has condemned U.S.-Israeli strikes and called for an immediate ceasefire against a country it has drawn closer to in recent years.

Iran last year sealed a 20-year strategic partnership agreement with Moscow, Russia is building two new nuclear units at Bushehr, the site of Iran's only nuclear power plant, and Iran supplied Russia with shahed drones for use against Ukraine.

MOSCOW, March 5 (Reuters) - Russia on Thursday accused the United States and Israel of trying to drag Arab countries into a wider Middle East conflict by provoking Iran into striking targets across the region and said there was no sign Washington and Tel Aviv would let up.

Arab states in the Gulf, all close U.S. allies - some of which also have close ties with Russia - have come under Iranian drone and missile attacks since the United States and Israel launched their air strikes on Iran on Saturday.

ANKARA, March 5 (Reuters) - Turkey said on Thursday that it was closely following the actions of the Iranian Kurdish PJAK militant group, which it said threatened Iran's security and regional stability, amid reports of discussions between Iranian Kurdish militias and Washington about the U.S. and Israeli war against Iran.

On Tuesday, sources told Reuters that the Iranian Kurdish groups had consulted with the U.S. about whether, and how, to attack Iran's security forces in the western part of the country.
