Martin seeks answers after Hassan killer goes missing
In a letter to be delivered this morning, Mr Martin is expected to tell his Iraqi counterpart he is concerned about reports that Ali Lufti Jassar al-Rawi, serving a life sentence for murdering the Dublin-born aid worker in 2004, has escaped custody.
The body of 59-year-old Ms Hassan has never been found and the minister believes the Iraqi government must provide assistance in locating it because her family want to give her a christian burial.
