In the land Jemen there is a severe war. The Huthi-Miliz fights against the government. Now the fighters control the full coast at the Red Sea. They control the sea strait now.
This is a big problem for world trade. Many ships drive through this sea strait. About 12 percent of all goods take this way. Now the rebels attack ships there.
Especially Saudi-Arabien has problems now. The land sells much oil to other lands. Earlier the ships used another way. But this way is blocked now. Therefore they use the Red Sea.
Now ships must drive a big detour. They drive around the continent Afrika. This takes 10 to 14 days longer. Therefore the prices for gas rise. In the USA diesel costs much money.
Experts say: The oil becomes even more expensive. The Huthi-Miliz gets help from the land Iran. Iran uses the power for own goals.
