Hamas vows 'volcano of revenge' for leader's death
Elsewhere in the Middle East, Spain's new Prime Minister Jose Luis Rodriguez said he has ordered his country's 1,300 troops out of Iraq on a weekend which saw 10 US Marines killed.
Rantissi was killed late on Saturday when an Israeli helicopter fired rockets into his car in Gaza City, less than a month after Hamas's spiritual leader Sheikh Ahmed Yassin was killed in a similar attack.
