French President Francois Hollande has urged the immediate release of two French journalists missing in Syria.
French radio station Europe 1 said one if its reporters and a photographer have been missing since June 6.
The two were reportedly headed for the northern Syrian city of Aleppo.
Hollande called for their release at a news conference during a visit to Tokyo.
It's not clear who might be holding them.
Hollande declined to provide further information on the journalists so as not to endanger their lives.
But Europe 1 named the pair as reporter Didier Francois and photographer Edouard Elias.
The media-rights group Reporters Without Borders says that since the start of the uprising against Syrian President Bashar al-Assad's regime in March 2011, at least 24 journalists, including several foreigners, have been killed in Syria.
