A man claiming to be al-Qaida leader Osama Bin Laden has said in an audio message that the release of French hostages depends on the withdrawal of French troops from Afghanistan.
The message, broadcast by al-Jazeera Friday, said the French people will pay a "high price" for President Nicholas Sarkozy's policies.
He said Mr. Sarkozy's refusal to remove troops from Afghanistan is a "green light" to kill hostages.
Extremists are holding at least eight French hostages, five believed to be held in Niger, two in Afghanistan and one in Somalia.
