EU naval forces have conducted their first raid on pirate bases on the Somali mainland, saying they have destroyed several boats.
The EU forces were transported by helicopter to the pirate bases near the port of Haradhere.
Anti-piracy forces have been reluctant to attack mainland bases, fearing for the crew of captured ships.
Somalia-based pirates have seized vessels across the Indian Ocean and demand huge ransoms for their release.
They are believed to be holding about 17 ships and 300 crew.
The latest incident involves the Greek-owned oil tanker Smyrni which was hijacked in the Arabian Sea last week.
The Liberian-flagged tanker carrying 135,000 tonnes of oil is reported to be heading for Somalia. . .
