Family and friends of international aid worker Margaret Hassan held a memorial service at London's Westminster Cathedral Saturday.
The Roman Catholic Archbishop of Westminster, Cardinal Cormac Murphy-O'Connor, presided over the funeral mass.
Unknown militants kidnapped Mrs. Hassan, the director of the Baghdad office of Care International, in October. A video released to the Arabic news channel Al-Jazeera in November showed the murder of a western woman, believed to be Mrs. Hassan.
Her body has never been recovered. But family members and British officials say they believe she is dead.
Mrs. Hassan was born in Ireland, but lived in Iraq for 30 years and was married to an Iraqi.
