On the day before the Gaza flotilla confronted the Israeli navy, Al-Jazeera TV documented the pre-battle atmosphere created by men on board the flotilla, who chanted a well-known Islamic battle cry invoking the killing and defeat of Jews in battle:
"[Remember] Khaibar, Khaibar, oh Jews! The army of Muhammad will return!"
Khaibar is the name of the last Jewish village defeated by Muhammad's army in 628. Many Jews were killed in that battle, which marked the end of Jewish presence in Arabia. There are Muslims who see that as a precursor to future wars against Jews. At gatherings and rallies of extremists, this chant is often heard as a threat to Jews to expect to be defeated and killed again by Muslims.
Al-Jazeera also interviewed a woman who said that the flotilla participants' goal was "one of two happy endings: either Martyrdom or reaching Gaza."
