Foreign Office Minister Tobias Ellwood has been responding to a written question by Labour MP Ian Austin.
The member for Dudley North asked "What steps he is taking to protect Christians from persecution by Islamic State".
In response Mr Ellwood said: "We are working closely with our international partners, including the UN and EU, to try to assist and protect civilians, including Christians and other minority groups, from ISIL.
"We are also in contact with senior political and religious leaders, including Canon Andrew White when he was in Baghdad, who played a key role in forming the High Council of Religious Leaders in Iraq and works closely with the Foundation for Relief & Reconciliation in the Middle East.
"Ultimately the only way to stop the suffering caused by ISIL, as well as countering the real and significant threat to the UK and our allies, is by defeating ISIL and establishing peace and stability in the region. We are working closely with our Coalition allies to achieve this."
Earlier this week Prime Minister David Cameron spoke of his desire to "destroy" Islamic State.
Speaking to US TV network NBC he said: "Look, we know that we have to defeat Isil, we have to destroy this caliphate, whether it is in Iraq or in Syria.
"That is a key part of defeating this terrorist scourge that we face.
"I want Britain to do more. I'll always have to take my parliament with me. We're talking and discussing at the moment, including with the opposition parties in Britain, what more we can do.
"But be it no doubt, we're committed to working with you to destroy the caliphate in both countries."
