Thi was a statement made early Friday.
Tui Travel said it was in continual contact with its 1,500 customers, of whom a majority had so far opted to continue their holidays. Up to 5,000 UK tourists are estimated to be in Tunisia in total.
So you can see they made the decision not to bring them home on Friday as TCX had done.
They made the decision Friday afternoon/evening to bring them home, they had already cancelled Sundays flights out, as had TCX before hand.
