CAFOD has already given Islamic Relief £100,000 and Christian Aid will soon hand over £250,000 and offer personnel support to the Muslim agency's work in Pakistan.
'CAFOD works with all people, regardless of their race, gender, religion or politics,' said spokesperson Claire Kirk. 'We are very happy to work with agencies of all faiths not only in times of emergency, but in our on-going work to eradicate poverty around the world'.
Waseem Yaqub, UK Manager of Islamic Relief, has just returned from visiting Pakistan where he saw the agencies working closely together.
'This is all really encouraging', he said. 'It just shows the faiths working together, which is what it should all be about.'
CAFOD and Islamic Relief have a long history of working together, for example, in Indonesia following last year's Tsunami and in Iran after the Bam earthquake in 2003.
This is the first time that Christian Aid has given financial support to Islamic Relief but has worked closely with them on advocacy work in the past, including in Afghanistan.
'The priority in any disaster relief work is to ensure that the poorest and most vulnerable people receive aid quickly and efficiently,' said Nick Guttmann, head of emergencies. 'Christian Aid works with people of all faith and none, and is delighted that we can offer Islamic Relief the assistance they need.'
Nearly £15 million has so far been raised for the DEC but agencies still need more money to ensure that people living in the far reaches of the affected areas get what they need.
