Leaders express relief at death of al-Zarqawi

World leaders and terrorism experts described the killing of Abu Musab al-Zarqawi as a blow to al-Qaida, but warned that his network of lieutenants would step up to carry on his campaign of death and destruction in Iraq.

The terror leader’s death in an airstrike in Iraq brought relief, tempered by caution, over the legacy of the Jordanian who forged an insurgency by force of his personality.
