France will stick to its timetable for withdrawing troops from Mali despite a resurgence in violence and the killing of two French journalists, its Foreign Minister Laurent Fabius has said.

The French government, which sent soldiers to its former colony in January to combat armed groups who had taken over large swathes of the country, has already delayed by two months plans to reduce troop numbers from 3,200 to 1,000 by the end of the year.

Speaking on Radio France Internationale, Fabius said France had moved 150 soldiers from the south to Kidal, the northerly Tuareg rebel stronghold, where instability has grown in recent months and where the journalists were abducted.

President Francois Hollande "immediately decided to strengthen our presence in Kidal, but that does not call into question the calendar and the reduction of French forces," Fabius said.

Malian troops and a UN peacekeeping force will also be reinforced, he said.

The Netherlands said last week it would send combat helicopters and around 380 troops to boost the UN mission in Mali, known as MINUSMA.

Speaking to journalists at the end of a visit to Mali on Tuesday, Secretary-General Ban Ki-moon said that troops for the UN mission, which eventually will number 12,000, were steadily arriving.

"The French operation is now in the process of withdrawing or exiting from their operation. That is why the United Nations Security Council, upon my recommendation, has established MINUSMA," Ban said.

"We are now in the process of deploying this mandated ceiling but we may have to wait a few more months."

Investigators arrive

France launched air strikes and sent troops into Mali in January to drive back advancing al Qaeda-linked rebels, fearing they could make Mali a base for attacks in other countries.

The Islamists scattered and a new president, Ibrahim Boubacar Keita, was elected in August.

Legislative elections are due on November 24, and Malian and international forces have launched a big operation against armed groups in the desert of northern Mali to prevent a recent surge in attacks.

Kidal itself has been thinly policed. About 200 UN peacekeepers are officially in control of security, with Malian forces largely confined to base. Most of the 200-strong French contingent is focusing on the Adrar des Ifoghas mountains, a hideout for militants.

Seven French investigators arrived in Mali to on Tuesday support the hunt for the killers of the RFI radio journalists, Claude Verlon and Ghislaine Dupont, a police source said.
