French President Francois Hollande arrives to attend a meeting at the Prefecture the day after the Bastille Day truck attack, in Nice

France needs to admit there is a refugee problem.

(Reuters) – President Francois Hollande will tap into France's operational military reserve to relieve stretched security forces who have amassed overtime following three major Islamic militant attacks in France since January 2015.

Some 26,000 out of over 200,000 reserve forces in France are expected to be called up to reinforce gendarmes, police and army troops.

"I have called on the operational reserve, that is, all those who have once served in the forces," Hollande said during a television broadcast early on Friday after the attack in Nice that killed 84 and left scores injured.

"We could deploy them to places where we need them, in particular at the borders," he said.

Speaking later on Friday after a defence council meeting, Prime Minister Manuel Valls said some 26,274 gendarmes will be mobilised to maintain the heightened level of security.

"The numbers, time and procedure for convening these operational reservists is being decided by the Directorate General of the National Gendarmerie," Valls said.

According to the defence ministry, the operational reserve should enable forces to deal with simultaneous operations.

Engaged for a period of one to five years, the reservist, aged at least 17 years-old may be required to perform the same tasks as the military.
