Togo's request to play at the Africa Cup of Nations has been turned down by the tournament organisers.
The squad flew home on Sunday in the wake of Friday's gun attack, which killed three people.
The country's sports minister then lobbied the Confederation of African Football (Caf) to allow the team to take part after three days of mourning.
But Caf, which initially wanted Togo to remain in Angola, gave no reason for its decision to exclude them.
