French President Francois Hollande and Russia’s Vladimir Putin agreed to share intelligence information and cooperate on selecting targets in the fight against ISIS, raising hope for closer ties between Moscow and the U.S.-led anti-ISIS coalition following the Paris terror attacks.

Putin said that Russia is ready to more broadly coordinate its military action in Syria with the U.S.-led coalition, but he harshly criticized Washington for failing to prevent the downing of a Russian warplane by NATO member Turkey. Hollande said Tuesday’s shoot-down of the Russian jet was a “serious incident, obviously regrettable” that underlined the need for closer coordination between the nations which are fighting ISIS.

“It is crucial in that period to avoid any risk, any incident, and prevent any escalation,” Hollande said at a news conference following the Kremlin talks.

“The only goal we must have is fighting Daesh and neutralize the terrorists, there is no other goal,” he said, referring to the ISIS by its Arab acronym.
