European Union maritime officials say Somali pirates have captured a Yemeni fishing vessel and its eight crew members in the Gulf of Aden.
The EU anti-piracy task force said Friday it had no details about the vessel Alfardous and its crew since it was seized on Sunday.
International naval patrols off the coast of Somalia have had little success in stopping pirates from attacking ships in the Gulf of Aden and Indian Ocean.
Somali pirates have made hundreds of millions of dollars in recent years hijacking and holding ships for ransom.
