PARIS/BAMAKO France said on Sunday two French journalists found dead in the northern Mali region of Kidal had been "coldly assassinated" by militants and vowed to step up security measures in the area.
Radio journalists Claude Verlon and Ghislaine Dupont were abducted after interviewing a member of the MNLA Tuareg separatist group in northern Mali.
Their bodies were found on Saturday by a French patrol 12 km (8 miles) outside Kidal, the birthplace of a Tuareg uprising last year that plunged Mali into chaos, leading to a coup in the capital Bamako and the occupation of the northern half of the country by militants linked to al Qaeda.
Adama Kamissoko, the governor of Kidal region, said French and Malian security officials were jointly investigating the attack, but French Foreign Minister Laurent Fabius put the blame firmly on militants operating in the region.
"The assassins are those that we are fighting, the terrorist groups that refuse democracy and elections," Fabius said, calling the killings "heinous and revolting".
Fabius said one of the journalists had been shot twice, and the other three times. He said French forces had tried to find the hostage takers, but to no avail.
Paris launched air strikes and sent thousands of soldiers into Mali at the start of the year to drive back al Qaeda-linked rebels it said could turn the West African country into a base for international attacks.
Islamists scattered during the French assault and a presidential election was held in July. But the journalists' deaths follow a number of attacks elsewhere in northern Mali, underscoring the fragile gains in the vast desert zone.
Last month Malian and international forces launched a wide-scale operation to keep pressure on Islamist groups.
Although Malian, U.N. and French troops are stationed in Kidal, none are heavily deployed. The Malian army's contingent is generally symbolic and soldiers are confined to their base.
There are some 200 U.N. peacekeepers (MINUSMA)who are officially in control of security and France also has about 200 troops, though their operations in the region have focused on the Adrar des Ifoghas mountains to the north, which served for years as a hideout for militants.

"Security in the area and the surrounding areas will be increased," Fabius said after a specially convened cabinet meeting. He did not elaborate.
Mali government spokesman Mahamane Baby echoed those comments saying President Ibrahim Boubacar Keita and Hollande had agreed that the status quo could not remain during a telephone call late on Saturday.
"The two heads of state agreed that the situation in Kidal was unacceptable and that a change was necessary to ensure the security of all Malians and foreigners present there," he said.
According to the Ouagadougou agreement signed by Mali's government and rebel groups ahead of the July elections that aimed to pave the way for a peace deal across the country, rebel fighters were due to be confined to barracks before the new government launched a final round of peace talks.
However, MNLA fighters still operate in and around Kidal, much to the frustration of Bamako.
The journalists' deaths came just days after four French hostages kidnapped in Niger by al Qaeda's north African (AQIM) wing were released following secret talks with officials from the West African country. They had been held for three years.
Paris dismissed media reports the government had used public funds to pay a ransom of some $20 million.
Pierre Boilley, an Africa expert at the Centre for National Scientific Research (CNRS), said the attack was likely to have been carried out by groups linked to AQIM or those trying to undermine talks between the government and northern rebels.
"It could also have been vengeance. There are difficulties within AQIM. Some may have benefited from the hostages' ransom, and others may have been neglected so it's a possible hypothesis," he said.
