Colonel Cyrille Duvivier, a spokesman for the French Air Force, told Reuters one or several Russian planes were detected and that the actions were not hostile.
"The usual response mechanisms were triggered: Rafale fighters took off in the late morning from the base of Saint-Dizier with a refueling plane and positioned themselves for possible intervention," Duvivier said.
RAF jets regularly monitor Russian warplanes near UK airspace and they intercepted jets near Romania last month.
Britain's Minister of State for the Armed Forces, Mark Lancaster, spoke about "an ever more assertive Russia" in a speech in London in July.
He said the RAF has had to scramble jets more than 80 times over the last decade to intercept Russian military aircraft.
