MOGADISHU, Somalia – Five of the pirates who hijacked a Saudi supertanker drowned with their share of a $3 million ransom, a relative said Saturday, the day after the bundle of cash was apparently dropped by parachute onto the deck of the ship.

The Sirius Star and its 25 crew sailed safely away Friday at the end of a two-month standoff in the Gulf of Aden, where pirates attacked more than 100 ships last year. Hundreds more kidnapped sailors remain in the hands of pirates.

The drowned pirates’ boat overturned in rough seas, and family members were still looking for four missing bodies, said Daud Nure, another pirate who knew the men involved.

Abukar Haji, uncle of one of the dead pirates, blamed the surveillance by a coalition of nations for the accident that killed his pirate nephew Saturday.

“The boat the pirates were traveling in capsized because it was running at high speed because the pirates were afraid of an attack from the warships patrolling around,” he said.

“There has been human and monetary loss but what makes us feel sad is that we don’t still have the dead bodies of our relatives. Four are still missing and one washed up on the shore.”
