Russian is ready to coordinate with the West over strikes on Syria, Putin says

President Vladimir Putin of  Russia late Thursday said he was ready to coordinate strikes against the Islamic State with the United States and its allies but warned that acts like the Turkish downing of a Russian jet could destroy any chance of collaboration.

After talks with French President François Hollande at the Kremlin, Putin said, "We are ready to cooperate with the coalition which is led by the United States."

It was the most forthright commitment to a joint effort between Russia and the West since Moscow's seizure of Crimea from Ukraine in 2014.
