Islamic State militants pressed for a ransom before killing journalist James Foley and are threatening to kill three other US hostages if their demands are not met, an American newspaper claims.
The New York Times, citing a representative of Foley's family and a former fellow hostage, reports that the US refused demands to pay a "multimillion-dollar ransom" for his release.
The newspaper claims that IS is also threatening to kill at least three other Americans if it does not receive ransom payments.
The report follows interviews with "recently released prisoners, family members of the victims and mediators attempting to win their freedom".
Many European nations have previously agreed to pay ransoms for hostages held by terror organisations, though Britain and the United States have continually said they will not.
A British family have told ITV News of their devastation after discovering a close relative is fighting with the Islamic State in Iraq.
A French journalist who was held hostage with James Foley in Syria has told ITV News it was "devastating" to see his murder.
