Here is a translation of the short letter:
"Dear Mr President,
It is with great emotion that the Duchess and myself have learned about the catastrophe in Beirut.
It is a dramatic event that touches us all.
Together with the people of Luxembourg we would like to express our profound sympathy with the people of Beirut in general. Our feelings of compassion go out to the families most affected by this tragedy.
Yours sincerely,
Grand Duke Henri"
