Dozens of foreigners have been killed, injured, or taken hostage during a surprise attack on Israel by the Palestinian militant group Hamas that has left 800 people dead, mostly Israelis.

Many of the missing foreigners were at an electronic music festival in the southern Israeli desert, at which scores of revelers were massacred.
