to the Knesset Foreign Affairs and Defense Committee that some of the vessels had been tampered with to halt them far from the Gaza or Israeli coast. According to UPI press coverage, the officer alluded to "grey operations" against the flotilla and said that no such action had been taken against the Mavi Marmara out of fear that the vessel might be stranded in the middle of the sea, endangering the people on board. Israel was accused of sabotaging activist ships in the past but no evidence has been found to back up these claims. Three ships – the Rachel Corrie, the Challenger I and the Challenger II – suffered damage or malfunction. While the Challenger I was able to continue, the Challenger II had to turn back halfway through the journey and Rachel Corrie docked for repairs in Malta. Greta Berlin of the Free Gaza Movement said that electric wires may have been tampered with. Raid and aftermath Israeli forces raided the flotilla on the night of 30–31 May 2010 in international waters of the Mediterranean Sea, boarding the ships using speedboats and helicopters. Nine activists were killed. Dozens of activists and seven Israeli soldiers were injured. After the raid, the activists were detained in Israel pending release: all were deported by 6 June. The ships were towed to Israel and those claimed by their owners were returned. The aid was delivered to Gaza under United Nations supervision on 17 June. Widespread international condemnation of and reaction to the raid followed. Various investigations were conducted, including by the United Nations, Israel and Turkey. Israel-Turkey relations were strained, and Israel subsequently eased its blockade on Gaza. Subsequent events Freedom Flotilla II Freedom Flotilla II sailed in June/July 2011.
