(ANSAmed) - NAIROBI, NOVEMBER 20 - Somali pirates who seized the Saudi super tanker Sirius Star have demanded 25 million dollars in ransom money from the owners of the ship, and have set the deadline as ten days from today, in exchange for which they will hand over the Sirius Star and its crew, who at the moment are being held hostage. Reports were from the pirates themselves to AFP. ''We want 25 million dollars from the Saudi owners of the oil tanker. We have no intention of discussing the matter,'' said Mohamed Said, one of the pirates who spoke over a satellite phone from the Sirius Star. ''The Saudis have ten days to comply'' with the request, ''otherwise we will react in a manner which could be disastrous,'' he added. On Saturday the pirates captured the super tanker loaded with 300,000 tonnes of oil. Since Tuesday the Sirius Star has been anchored in the Somali port of Harardere, 300 kilometres north of Mogadishu. The news of the request for 25 million dollars in ransom was later confirmed, without adding any further details, by a Kenyan member of Parliament, Ferdinand Waituto. The super tanker was seized by Somali pirates on Saturday, 800 kilometres south of Mombassa (Kenya), about a thousand kilometres from the normal range of action for the pirates, which is leading to adjustments in military strategies to fight against them. Onboard the oil tanker (launched in April, it is 330 metres long with a tonnage of over 13,000, and a value of 150 million dollars) there are two million barrels of crude oil, worth over 100 million dollars.
