MOSCOW (AP) -- Russian officials say British and Chinese experts have joined a panel investigating the downing of a Russian warplane by Turkey.
Russian defense ministry officials said Friday that Russian and foreign experts would study data contained in the plane's flight recorder.
Turkey said it shot down the plane on Nov. 24 after it violated its airspace for 17 seconds. Russia insisted the plane was in the Syrian airspace.
The recorder was recovered by Russian and Syrian forces from the area in rebel-controlled northern Syria where the plane was shot down.
