The Turkish army has suspended flights over Syria as part of an ongoing joint military campaign with the United States against the Islamic State of Iraq and the Levant (ISIL) after it shot down a Russian jetfighter, sparking an unprecedented crisis between Ankara and Moscow.

The decision was taken following the eruption of the crisis with Russia in which a Turkish F-16 downed a Russian warplane early Nov. 24 after it allegedly violated Turkish airspace, according to diplomatic sources.
