France says Russia could face war crimes charges over its bombing campaign of Syria's eastern city of Aleppo.
French Foreign Minister Jean-Marc Ayrault said Monday that the bombings are war crimes.
Ayrault said France would consult with prosecutors from the International Criminal Court (ICC) to see how to launch investigations.
"We do not agree with what Russia is doing, bombarding Aleppo. France is committed as never before to saving the population of Aleppo," Ayrault said.
Moscow has repeatedly denied attacking civilians in Syria, and says it targets terrorist groups.
It is not clear how the ICC could investigate the bombings in Aleppo because neither Russia nor Syria is a member of the International Criminal Court. The matter could be referred to the court by the U.N. Security Council, but the council has been deadlocked over Syria.
