Answering a written question, Foreign Office Minister James Duddridge responded to Christian DUP MP Jim Shannon, who questioned: "What discussions he has had with the new Prime Minister of Nigeria on the situation of the Christian minority in the north of that country".
In his response Mr Duddridge said the Prime Minster and Foreign Secretary had held talks with President Buhari to underline their concerns.
He said: "Boko Haram's attacks are often indiscriminate and they commit appalling atrocities against all those, both Christian and Muslim, who do not follow their extremist and intolerant views.
"We condemn their actions unreservedly. As the Prime Minister, my right hon. Friend the Member for Witney (Mr Cameron) informed colleagues on 10 June, we have equally underlined to the President our commitment to helping him tackle the threat.
"The UK is providing a substantial and increasing package of intelligence, military and development support, including programmes working with religious leaders to directly address conflict in northern Nigeria and training and advice to Nigerian units deploying against Boko Haram.#
Boko Haram has been behind many attacks on churches and Christian communities in Nigeria. It's claimed its leaders want to create a fully Islamic State. Currently the country is made up of 51% Christians and 46% Muslims. Christians tend to preside in the south of the country while Muslims tend to live in the north.
