Haiti's political opposition has rejected a US-backed power-sharing plan aimed at ending the country's crisis.

They have refused to take part in any government which includes President Jean-Bertrand Aristide, and insist he must resign.
Mr Aristide - who had agreed to the plan - has called for international help to end the rebel uprising.
The rebels control much of the north of the country and threaten to move into the capital Port-au-Prince within days.
The political opposition, which does not back the armed rebellion, said it would accept nothing short of Mr Aristide's resignation.
"We sent our position and a signed letter saying no to the proposal," Paul Denis of the opposition Democratic Platform told the Associated Press.
The announcement came after a deadline expired for them to respond to the plan. That deadline had been extended for 24 hours on Monday in the hope of reaching an agreement.
The plan would leave President Aristide in place until 2006, but with reduced powers.

"Should those killers come to Port-au-Prince, you may have thousands of people who may be killed," he told a news conference.

Rebel factions have already overrun the country's second city, Cap-Haitien and the territory under their control is said to be rapidly descending into lawlessness.
The BBC's Stephen Gibbs in Port-au-Prince says rebel leaders have been speaking in confident mood about the type of rule they aim to establish if, as they intend, they take over.
They say that the army would be reformed but that their government would not be a military one.
Haiti's neighbours have said they will not accept the overthrow of the democratically-elected Mr Aristide, whose is accused by his opponents of rigging elections four years ago.
