Oil prices increased after the attacks on oil plants in Saudi Arabia. It was the biggest rise in ten years. Prices went up by nearly 20 per cent - the biggest one-day rise since the 1990-91 Gulf War. Saudi said the drone attacks cut the country's oil production in half, and global oil production by five per cent. It could take weeks to fix. We could pay higher gasoline prices. People may also have to pay higher prices for food and other things.
Yemen's Houthi group said it carried out the attacks because of Saudi attacks on its groups in Yemen. Iran supported this claim and called it self defense. It said: "The attack was a...response to years of Saudi aggression against Yemen." Arab countries say there is evidence that weapons used in the attack were made by Iran. U.S. officials say the attacks came from either Iraq or Iran, not Yemen. Iran called this "maximum lies".
