Togo's request to return to the Africa Cup of Nations has reportedly been turned down by the Confederation of African Football.
The squad left Angola and returned home on Sunday for three days of national mourning following the attack on their team bus which left three members of the support staff dead and reserve goalkeeper Kodjovi Obilale hospitalised with gunshot wounds.
Manchester City's Emmanuel Adebayor and Moustapha Salifou of Aston Villa were both unhurt in the attack.
Togolese sports minister Christophe Tchao had appealed to the Confederation of African Football (CAF) to keep his country's place in the tournament open despite their departure.
However, his request to remain part of a rescheduled tournament is believed to have fallen on deaf ears.
"We have ordered a three-day (period of) mourning," said Tchao on Sunday.
"The players are leaving with the bodies of their fallen brothers and we have asked the Confederation of African Football to find an arrangement so we can catch up with the competition later."
Togo's departure from the competition has left Group B with just three sides - Ivory Coast, Burkina Faso and Ghana.
Meanwhile, Angolan police are reported to have arrested two people in connection with the attack.
A group calling itself the Front for the Liberation of the Enclave of Cabinda had claimed responsibility for the 30-minute attack.
