Houthi rebels in Yemen have detained 10 ships, according to the country's government.
The claim was made by Saudi Arabian state TV channel Al-Ekhbariya.
Tankers and cargoships are among those held at the port of Hodeidah, the report said.
Yemen's minister of local administration Abdul-Sareq Fatah said the militia had prevented ships from unloading their cargoes, which included food.
He called on the United Nations’ humanitarian coordinator in Yemen, Lisa Grande, to intervene.
