Rate of suicide bombs rises in Iraq.

Figures supplied at Gen. David Petraeus’s year-end briefing to journalists “showed a slight rise in suicide car and vest bombs since October.” Petraeus also emphasized that recent security gains in Iraq are “reversible.” “Although the security situation has improved this year, U.S. commanders have been careful not to declare victory after years in which their statements were often seen as overly optimistic,” Reuters adds.
