NAVFOR said that Virgin Islands-owned chemical tanker MV Theresa VIII was attacked 180 nautical miles northwest of the Seychelles in the Indian Ocean on Monday. The ship was heading for the Kenyan port of Mombasa, but has been turned north and is presumably heading for the Somali coast. Ukrainian craft MV Lady Juliet was attacked by pirates firing Kalashnikovs and rocket propelled grenades, but were repelled by a Vessel Protection detachment (VPD) from NAVFOR.
