Another vessel seized off Somali coast as threat level increased

"Due to the increased threat of possible PAG (Pirate Action Group) activity, vessels are advised to transit with caution," the UKMTO said in a statement, noting that weather is conducive to small boat operations.

Pirates also hijacked an oil tanker, Honour 25, with 17 crew that was sailing near the Somali coast on 22 April, according to multiple security officials speaking to the BBC.

Under the control of the pirates, the vessel, carrying 10 Pakistanis, four Indonesians, one Indian, one Sri Lankan and one from Myanmar, anchored close to the Somali shore between the fishing towns of Xaafun and Bander Beyla.
