All threats to UK forces in Iraq are kept under constant review. This includes the threat posed by surface to air missiles. I am withholding further details as it would, or would be likely to, prejudice the capability, effectiveness and security of our armed forces.
I hold regular discussions with the US Defense Secretary on issues of mutual interest, including the situation in Iraq.
Iran is an influential neighbour in the region and its behaviour continues to be a cause for concern. We and the US continually assess the nature of insurgency in Iraq including the influence of outside groups.
Support from within Iran, including the Quds Force, goes to groups who are attacking our forces and fuels the sectarian violence in Iraq. In our assessment some of the improvised explosive devices that are being used against our forces use technology that originates from Iran.
Iranian links to illegal armed groups either through supply of weapons, training or funding, are completely unacceptable. We have said so and so have the Iraqi Government.
