His Royal Highness was addressing church members of the Iraqi Chaldean Christian Community in Acton, West London, some with families in Iraq directly affected by the ongoing persecution of Christians in the Middle East by ISIL or ISIS present.
The Prince suggested a 'greater duty of care' was needed, especially to the victims of violence and their families in Iraq and Syria, who he said are left 'distraught' by the graphic images that are being transmitted around the world on a daily basis.
Receiving a standing ovation from the congregation, before delivering a heartfelt speech on an issue which he continues to highlight, he said: "Having heard some of the accounts and the stories of unbearable suffering before I came into the church from members of your community, I feel extraordinarily inadequate in trying to express how much I feel for what all of you are forced to go through."
Such indescribable agony. And the fact that I can be here with you briefly on this occasion is merely a way of trying to show how much we feel for you ".
One church member, Margo Yako, a UK resident for many years revealed to the Prince how other family members managed to escape with her elderly aunt, a stroke victim, as I.S. militants attacked the mainly Christian town of Mosul this summer.
Ms Yako said her family was now living in temporary accommodation in Northern Iraq, with little expectation of returning home.
The Prince has continued to raise the issue of religious persecution, particularity against Christians in the Middle East over the past year, most recently describing threats to Christians there as "an indescribable tragedy" at the launch of a report into religious freedom.
The Prince told the congregation that hearing the Lord's Prayer in Aramaic made him feel closer to the victims of violence in the Middle East, while he also noted the Chaldean choir's performance as am 'enormously special treat'.
Premier can also reveal the Prince has made a 'substantial' personal donation to one of Aid to the Church in Need's camps in Syria, benefitting 8,000 victims of violence.
Catholic Archbishop Habib of Basra also presented the Prince of Wales with a gift, a personal family Bible dating back to 1895.
There are approximately 4000 Iraqi Chaldean Christians in the U.K. Catholic Chaldeans have been in Britain since end of the 19th Century. There are no definite records available to show where they settled. The Chaldean Patriarch Immanuel visited Britain in 1920 to reveal to the authorities the challenges facing Christians in Iraq and Turkey as the consequences of First World War.
It is believed that over one hundred families settled in United Kingdom during the 1970's. There was an increase in the 1980s due to the Iran-Iraq war.
