Tunisia's National Dialogue Quartet, which on Thursday picked up its Nobel Peace Prize at a formal ceremony in Oslo, said the fight against terrorism was an "absolute priority".

"Today we are in a great need of dialogue between civilisations and peaceful coexistence ... Today we need to make the fight against terrorism an absolute priority," said Houcine Abassi, the secretary general of the Tunisian General Labour Union, one of the four members of the Quartet.
