On the morning of May 31, 2010, IDF naval forces intercepted six ships from the IHH organization attempting to break the naval blockade of the Gaza Strip.
After the ships ignored numerous warnings to redirect toward Ashdod, where their material could be checked and then transferred to Gaza, teams of elite naval commandos boarded the vessels. On the lead boat, the Mavi Marmara, demonstrators onboard attacked the IDF personnel with live fire, light weaponry, knives and clubs. Two weapons were also taken soldiers and used against them.
As a result of the violence, seven soldiers were wounded and nine Turkish citizens were killed.
