Some UN relief money was channelled through charities associated with extremist jihadi groups in the wake of the 2005 Pakistan earthquake, a BBC investigation has found.

Uh huh. No surprise there...

There followed a mass mobilisation by ordinary Pakistanis, non-governmental organisations and Muslim groups to help the survivors. Various charities associated with militant groups also responded.

They included the al-Rashid Trust, which is banned by the UN Security Council and accused of being a conduit for al-Qaeda financing. The group is also on Pakistan's own terrorism watch list.

But the UN on the ground delivered aid to relief camps controlled by al-Rashid - tents, trucks, medicine, blankets and schools.

UN agencies also worked with Jamaat ud-Dawa, another charity which the US state department claims has close associations with the outlawed militant group, Lashkar-e-Toiba.

The UN denies "working with" the groups, but says that they (the UN) were "active in the camps that were run by them."

But at one of their schools in the town of Mansehra - set up initially with the help of the United Nations Children's Fund, Unicef - primary children were singing a song at morning assembly which many might find disturbing.

It includes the line: "When people deny our faith, ask them to convert and if they don't, destroy them utterly."

I asked the Jamaat ud-Dawa spokesman, Abdullah Montazzer, why they were teaching such bloodthirsty songs to young children.

"No, they weren't singing that," he said. "Lots of infidels came in the aid effort and they weren't harmed. I don't believe these kids were singing these kind of songs."

Infidels? Why the fuck do we keep helping these people?
