assistance

163. Insofar as the Israeli interception of the flotilla was unlawfuland the Mission considers that it was unlawfulthe use of force by the Israeli forces in seizing control of the Mavi Marmara and other vessels was also prima facie unlawful since there was no legal basis for the Israeli forces to conduct an assault and interception in international waters.
170. The circumstances of the killing of at least six of the passengers were in a manner consistent with an extra-legal, arbitrary and summary execution.
176. The mass detention of more than 700 passengers and crew on board the six vessels had no basis in law, was arbitrary in nature and is a violation of Article 9 of the International Covenant on Civil and Political Rights.
203. Some passengers in the passport checking area saw an older passenger being roughly treated after receiving what appeared to be a beating. When other passengers, including Irish and Turkish, protested at this treatment, they were charged by soldiers using batons. In the foray, around 30 passengers were beaten to the ground, kicked and punched in a sustained attack by soldiers. One Irish passenger was seen being particularly badly beaten around the head and held in a choke position to the point of near suffocation. He identified his attackers as police officers. He was taken to a holding cell.
208. There were other incidents of isolated violence against individual passengers who were deemed to be uncooperative. One passenger was seen having his arm twisted behind his back by police to the point that the arm broke. Another was kicked and hit by some ten soldiers, handcuffed and taken by vehicle to another place 10-15 minutes away, where soldiers abused him for up to two hours. When he returned to the airport, he was bleeding from the head.
265. The Mission considers that several violations and offences have been committed. It is not satisfied that, in the time available, it can say that it has been able to compile a comprehensive list of all offences. However, there is clear evidence to support prosecutions of the following crimes within the terms of article 147 of the Fourth Geneva Convention:
wilful killing;
torture or inhuman treatment;
wilfully causing great suffering or serious injury to body or health.
The Mission also considers that a series of violations of Israels obligations under
international human rights law have taken place, including:
right to life (article 6, ICCPR);
torture and other cruel, inhuman or degrading treatment or punishment (article 7,
ICCPR; CAT);
right to liberty and security of the person and freedom from arbitrary arrest or
detention (article 9, ICCPR);
right of detainees to be treated with humanity and respect for the inherent dignity of
the human person (article 10, ICCPR);
freedom of expression (article 19, ICCPR).
