Paris on Sunday blamed terrorist groups for the ?odious? and ?cold-blooded? murder of two radio journalists in northern Mali, and said French troops would boost security in the restive zone.
Foreign Minister Laurent Fabius said Radio France Internationale (RFI) journalist Ghislaine Dupont and sound technician Claude Verlon were shot dead after being abducted by armed men on Saturday.
?They were killed in cold blood, one took two bullets and the other three,? he said after crisis talks led by President Francois Hollande on the murders in the northeastern town of Kidal.
?The killers are those we are fighting, the terrorist groups who are opposed to democracy and elections,? he said, adding the journalists had been executed in an ?odious manner.?
He said security in ?the entire zone and neighbouring areas, in particular with concern to French citizens, will be intensified.?
A government source said this meant making the presence of French troops based in northern Mali ?more visible.?
Justice Minister Christiane Taubira and the head of France?s external intelligence services agency Bernard Bajolet also attended the hour-long talks with Hollande.
Dupont, 57, and Verlon, 55, had travelled Saturday to Kidal to interview a spokesman for the Tuareg separatist group the National Movement for the Liberation of Azawad (MNLA), and were abducted outside his home, according to their employer.
They were both veteran journalists experienced in Africa reporting. Dupont had spent 27 years covering the continent since joining RFI in 1986.
