A memorial mass takes place in England today for the murdered Dublin-born aid worker, Margaret Hassan.
The 59-year old director of CARE International in Iraq, was kidnapped by gunmen on October 19 while on her way to work in western Baghdad.
On November 16, the Arab satellite station Al Jazeera said it had received a videotape showing the murder of a Western woman - believed to be her.
Her family then released a statement saying that they feared she had been killed by her captors.
Mrs Hassan's body has so far not been found. The service takes place at Westminster Cathedral this lunchtime.
