US soldiers stopped two oil ships. This is a strong move. It is against Venezuela's oil. One ship had a Russian flag. The US wants to follow rules.
The Russian ship was called Marinera. It sailed for two weeks. US soldiers came by helicopter. The UK navy also helped. Another ship, M/T Sophia, was stopped. It was in the Caribbean. It also had Venezuelan oil.
The US called Marinera a "shadow fleet" ship. It changed its flag. The US wants to stop Venezuela's money. This will put pressure on their leader.
Russia was not happy. They asked for their sailors. This could make things harder between the US and Russia.
The US wants to stop all Venezuela oil. This is a big plan. It might change things in Venezuela. We do not know what will happen next.
