The state-run Liberia Broadcasting System reports Wednesday there likely will be a runoff based on preliminary figures seen by its correspondents.
George Weah, former soccer player and presidential candidate of Congress for Democratic Change (CDC), votes at a polling station in Monrovia.
Unofficial early results announced by the station favored ex-soccer star George Weah of the Coalition for Democratic Change and Vice President Joseph Boakai of the ruling Unity Party.

International observers say Tuesday's vote went smoothly despite late voting starts in some counties.
The new president will replace Africa's first female democratically elected leader, Ellen Johnson Sirleaf, who is stepping down after two six-year terms.
Final results should be known within two weeks. If there is a runoff election it will come two weeks after that announcement.
