Liberia's Supreme Court has halted the second round of voting to determine the country's next president.
It says the poll cannot proceed until the electoral commission has "urgently and expeditiously" investigated claims of "irregularities and frauds".
Those claims were made by the Liberty Party's Charles Brumskine, who did not pass the first-round vote and is now challenging the result.
The winner will replace Nobel Prize winner President Ellen Johnson Sirleaf.
