A big meeting was planned in Oman. It should happen on Monday. Men from Iran and other countries wanted to talk. They want to talk about the Strait of Hormuz. That is a narrow part of the sea. Many ships with oil drive through this part. There is much trouble because of war.
Now the meeting is delayed. The foreign minister from Oman says: We need more peace. Saudi-Arabien asked to stop the meeting. Other countries do not want to come. One reason is the war in Yemen. There are rebels who fight.
The situation in the sea is very hard. Iran puts dangerous bombs in the water. Ships can only drive with danger. This makes oil very expensive. The USA and Iran fight about the ships. Both want to protect the ships.
