In Bouira, southeast of the capital, a vehicle carrying a family skidded off the road, killing a 10-year-old. Eight other passengers, including four children between the ages of 3 and 8, were also injured, said the state news agency.
The remaining two deaths occurred in the towns of Tipaza and M'Sila. Much of the north of the country was blanketed with heavy rains Tuesday, exacerbating the dangers of driving.
It is the country's fourth trip to the World Cup and follows closely on its 2010 appearance in South Africa.
Prime Minister Abdelmalek Sellal and other members of the government lunched with the victorious team on Wednesday. The absence of ailing President Abdelaziz Bouteflika was noted as another sign of his increasing infirmity following a stroke in April.
The 76-year-old president was nominated by his party Saturday to run for a fourth term.
