The White House has condemned the assassination of an anti-Syrian politician in Lebanon, two days after parliamentary elections.
Spokesman Scott McClellan called for a complete investigation into the killing of George Hawi, a former leader of the Lebanese Communist party.
He also criticized Syria's continued presence in Lebanon, saying it has created an environment of intimidation and political repression.
Lebanese police say Mr. Hawi died instantly Tuesday when a remote-control bomb destroyed his car in central Beirut.
A similar blast killed Lebanese newspaper columnist Samir Kassir earlier this month.
Meantime, United Nations investigators are continuing a probe into the assassination of former Prime Minister Rafik Hariri in February.
The killing sparked widespread political unrest in Lebanon and forced Syria to withdraw from the country. Mr. Hariri's son, Saad, then led an anti-Syrian alliance to victory in the polls.
