"Our thoughts tonight are with the people of S. Africa. Nelson Mandela's legacy will continue to burn brightly around the globe."
"Our thoughts go out to the people of South Africa who will be left heartbroken by this sad news.
"Every so often history produces an individual whose message is universal, and Nelson Mandela will be mourned and missed on every continent around the globe. The hope he offered was enough to unite races; it bridged cultures and transcended generations; and it could heal the deepest divides.
"That hope must now live on. Nelson Mandela's legacy will continue to burn brightly, there is little doubt about that. But our greatest tribute to him will be our commitment to equality, humanity and peace - the values for which he very literally put his life on the line."
