In a statement, the Mayor of Derry City and Strabane District Council, Lilian Seenoi-Barr said she offered "deepest sympathies" to Archbishop Eamon Martin, the clergy, and all members of the Catholic Church.

She said that there has been a "huge outpouring of sorrow and grief" across Derry and Strabane since Pope Francis' passing on Monday.
