Iraq's prime minister is in London today-Wednesday to meet with the British defense minister, following a British military raid Monday on a prison in the southern Iraqi city of Basra.
Ibrahim al-Jaafari's office has said there is no crisis in relations between the two allies, but several Iraqi officials have expressed anger over the raid, which resulted in the freeing of two undercover British soldiers allegedly held by an Iraqi Shi'ite militia.
The soldiers were arrested after allegedly shooting two Iraqi policemen.
British troops launched a rescue mission when they became concerned that police had handed the men over to a local militia.
Concerns have grown recently that insurgents have penetrated Iraq's security forces and police.
Iraq's national security advisor Mouwafak al-Rubaie admitted to British radio today Wednesday that such a problem exists in "many parts of Iraq." But he said new, tougher procedures are in place to root out such elements and stop future infiltration.
