Six pirates armed with guns and knives in a pirogue fishing boat, one dressed in military uniform and two with facemasks approached a yacht underway. The skipper rammed into the fishing boat but the pirates managed to board the yacht. They tied the two-crew members and pointed guns to their heads. They shot and stabbed the skipper’s dog. The pirates stole equipment, property, and left. One crew injured.

The ship activated SSAS and sent voice message to the coalition forces indicating pirates on board. The owners are unable to contact the ship and suspect all communication equipments have been damaged. There are 21 crew onboard the ship. Further details are awaited. (See here)

The speedboats suddenly approached the tanker and fired upon her. D/O raised alarm, sounded whistle and crew mustered. Pirates noticed crew alertness and reduced their speed and aborted the attempted boarding.
