In Saudi Arabia happens a drone attack. The attack hits an important oil pipe. Saudi Arabia stops the work of the line. This can raise the price for oil.
President Donald Trump thinks Iran is to blame. The drones start in Iraq. There live groups that Iran helps. But Iran says: We are not to blame.
In the land Yemen are fights too. The Huthi rebels take the whole coast. They control an important sea road now. This road is called Bab al-Mandab.
Many ships with goods drive through this sea road. The rebels stop ships from Saudi Arabia. They let other ships pass. Saudi Arabia has problems to sell oil now.
The crown prince of Saudi Arabia asks Donald Trump for help. But the USA do not send soldiers. They only give secret news. The USA do not want a bigger war.
Donald Trump thinks the war ends soon. He thinks the war ends in November. Then the price for oil goes down again. But experts are not sure.
