French Foreign Minister Laurent Fabius said Friday that major questions remained unresolved in talks in Geneva that have raised hopes of a deal on Iran's disputed nuclear program.

Spain has released a member of the far-left group Grapo who was arrested last year in connection with the kidnapping and death of a Spanish businessman in 1995, officials announced Friday.

France will issue an unprecedented invitation to all 72 countries involved in World War I to take part in its annual Bastille Day military parade in July next year, President Francois Hollande announced Thursday.

Paris has "fairly recent" proof that four French journalists kidnapped in war-torn Syria are alive, Foreign Minister Laurent Fabius said in a television interview on Thursday.

France said on Thursday that al-Qaida's north African branch may have killed two French journalists in Mali at the weekend, as the group had earlier claimed.

"We're in the process of verifying it, but it seems plausible," French Foreign Minister Laurent Fabius told French television, referring to the claim over the murders of Ghislaine Dupont and Claude Verlon in the flashpoint northeastern town of Kidal on Saturday.

Al-Qaida's African division claimed responsibility Wednesday for the murders of two French journalists in Mali's rebel-infested desert, saying they were killed to avenge France's "new crusade" in its former colony.

Ghislaine Dupont, 57, and Claude Verlon, 55, were kidnapped and shot dead by what French officials called "terrorist groups" after interviewing a spokesman for Tuareg separatists in the flashpoint northeastern town of Kidal on Saturday.

France's most prominent black politician has spoken out for the first time to voice her dismay at being subjected to monkey taunts and other racist abuse.

Brazil kept French spies under surveillance in connection with suspected sabotage at its Alcantara satellite launch base where a blast killed 21 people in 2003, a newspaper reported Tuesday.

A French woman who went missing during a transit stop in Egypt between flights was found on Tuesday, an official at the French embassy in Cairo said.

France said Tuesday it would stick to plans to withdraw most its troops from Mali, as the bodies of two French journalists killed in the country's restive north arrived in Paris.

Foreign Minister Laurent Fabius said 150 French soldiers had been sent to join 200 troops already in the flashpoint northeastern town of Kidal, where Radio France Internationale (RFI) journalists Ghislaine Dupont and Claude Verlon were killed on Saturday.
