French Foreign Minister Alain Juppe on Monday condemned firmly the "violent attacks" which rocked Nigeria's churches on Christmas Day.
In a statement posted on the ministry website, the French top diplomat sent his condolences to victims' families and the Nigerian government, denouncing the "outbreak of violence" in the African country.
"As I expressed to the Nigerian authorities during my visit there in November last year, France supports them in their fight against terrorism," Juppe added.
France's President Nicolas Sarkozy on Sunday also strongly condemned the Christmas Day bomb attacks in Nigeria.
Nigeria is France's biggest trading partner in sub-Saharan Africa with French oil giant Total among the major producers of crude oil in the country.
At least 39 people were killed in a series of bomb attacks targeted at churches across Nigera during this year's Christmas holidays. Islamist militants from Boko Haram group has claimed responsibility for the attacks.
