US Attorney General Eric Holder hailed the residents of Lockerbie, describing them as "generous" and "determined", as the 25th anniversary of the tragedy was marked in the UK and US today.
Mr Holder said that families and friends of the victims who then went on to fight a legal battle were "selfless". He added:
Although a quarter century has passed since the world was shaken and so many lives were devastated by a heinous and cowardly act of terror, no amount of distance or time can ease the pain or erase the loss that was inflicted on that day.
We keep calling for change and fighting for justice on behalf of those no longer with us. We rededicate ourselves and our nation to the qualities that define the men and women that we lost. And we continue to be drawn together on this day.
