Dozens of foreigners have been killed, injured or taken hostage during a surprise attack on Israel by the Palestinian militant group Hamas Saturday that has left 700 people dead, mostly Israelis.

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

Here is what we know so far:
