A French journalist working with the duo said that group was snatched by gunmen around 60 kilometres (38 miles) from the Afghan capital on Wednesday, Dec 30.
"The two journalists, accompanied by their Afghan translator, and the translator's brother and cousin, were kidnapped on the road between Surobi and Tagab," their French colleague said.
Blaming Taliban for the kidnapping, the colleague said that an ambush was laid for the group in the Kapisa province.
French Defence Minister Herve Morin after visiting the French troops in Afghanistan to celebrate the New Year has only said that the two journalists went missing since Dec 30.
The kidnap adds to list of foreigners, including journalists were abducted by criminal groups and Taliban insurgents since 2001 US-led invasion of Iraq.
