The House resolution, passed on April 25, also accuses the 22-member Arab League of obstructing the deployment of UN forces in Darfur or seeking to reduce the mandate of the forces.
"The secretariat of the Arab League expresses its extreme astonishment at the resolution … at a time when no international or regional organisation has used this designation (genocide)," a league statement said.
"The league also expresses its indignation at the resolution saying the Arab League has obstructed the deployment of UN forces in Darfur. This shows that incorrect information has been submitted to the US Congress on which to base resolutions which are far from reality," it said.
The Arab League statement defended the organisation’s diplomatic record on the Darfur conflict
