Qatar shot down two SU24 aircraft coming from Iran, the Qatari defence ministry said on Monday. It did not provide further details on the incident.
The war in the Middle East spiraled further as Israel and the US pounded Iran.
Tehran and its allies hit back against Israel, neighboring Gulf states, and targets critical to the world's production of oil and natural gas.
The intensity of the attacks, the killing of Iranian Supreme Leader Ayatollah Ali Khamenei, and the lack of any apparent exit plan set the stage for a prolonged conflict with far-reaching consequences. Safe havens in the Mideast like Dubai have seen incoming fire; hundreds of thousands of airline passengers are stranded around the globe; oil prices shot up; and US allies pledged to help stop Iranian missiles and drones.
Iran has long threatened, if attacked, to drag the region into total war, including targeting Israel, the Gulf Arab states and the flow of crude oil crucial for global energy markets. All of these came under attack on Monday.
The chaos of the conflict became apparent when the US military said Kuwait had "mistakenly shot down" three American F-15E Strike Eagles while Iran was attacking with aircraft, ballistic missiles, and drones. US Central Command said all six pilots ejected safely and are in stable condition.
