U.N. chief says another investigation into Hariri's assassination may be needed

U.N. Secretary-General Kofi Annan
told a summit of Arab leaders Wednesday that he expects
another more comprehensive investigation will be needed
into former Lebanese premier Rafik Hariri's assassination.
Annan said he expects to report in the next few days on a
fact-finding mission into Hariri's Feb. 14 death in a
massive car bomb. But "a more comprehensive investigation
may also be necessary," he said.
