Mr. Speaker, we strongly condemn the atrocities by the so-called Islamic State. Official recognition of genocide is to be done by a credible judicial process following a proper international investigation. That is why we have called upon the UN Security Council to investigate this. The UN Secretary-General's special adviser on the prevention of genocide agrees with this. We feel that our UN, U.K., and U.S. allies have all said this needs a proper, formal investigation.
