Oil is a fuel that ships carry around the world, and its price is quoted per barrel. On Tuesday, Brent crude, a main world price, ended at $108.82 a barrel. Fears about supply keep the price high.
Two sets of events are behind those fears. The Houthis, a group in Yemen, said on Monday that they attacked several Saudi Arabian sites. Saudi officials did not immediately confirm this, and Reuters, a news agency, said it could not verify it.
The second is about ships. Iran's Revolutionary Guards said their sea mines stopped three tankers near the Strait of Hormuz, and that two caught fire. US Central Command said those claims were false. Meanwhile Iran and the United States are still talking indirectly, through Pakistan and Qatar.
