The Amnesty International report is critical of the work of the UN troops

The report also accused the US-backed interim government and the UN peacekeeping force of showing leniency toward former soldiers and other rebels who toppled President Jean-Bertrand Aristide last year while aggressively combatting armed militants loyal to the ousted leader.

The interim government is further accused of failing to prevent or to investigate such serious human rights violations.

In its report, Amnesty claimed that arbitrary detentions, the deliberate killings of civilians and police abuse are common. The report contains a list of examples of what are called extra-judicial killings, carried out by the Haitian national police.

Amnesty International said based on its findings it is deeply concerned for the lives and the physical integrity of the people of Haiti.

The United Nations mission is also criticised for not implementing a proper disarmament programme.

Although UN troops drove former soldiers from police stations in several provincial towns earlier this year, Amnesty said the UN mission has seen its activities "limited by the lack of political will from the interim goverment to take a stance against these groups".

Both the Interim prime minister Gerard Latortue and leaders of the UN force in Haiti say they will review the report in full before commenting on it.
