Ten people were killed in a crush during a religious gathering in the Angolan capital on New Year's Eve.
Another 120 people were injured as they tried to enter an overcrowded stadium for the vigil in Luanda.
Four children were among the dead at the Cidadela Desportiva stadium.
Those who died were crushed and asphyxiated, according to a spokesman for the national firefighters department.
The event in the southern African nation was organised by the Universal Church of the Kingdom of God, an evangelical group founded in Brazil.
In Ivory Coast, western Africa, three days of national mourning have been declared after a fatal stampede during New Year's fireworks.
Up to 61 people died in the crush and more than 200 were injured.
Ivory Coast President Alassane Ouattara has ordered an immediate investigation into the causes of the stampede.
He said the government would open a crisis centre to help families find missing people and to take testimony from witnesses.
