Egyptian Interior Ministry spokesman Brig. Gen. Ayman Helmy denied in comments to Sputnik on Monday media reports alleging the existence of a Turkish lead in the downing of the Russian Airbus A321 passenger plane in Egypt in October 2015.

Earlier in the day, the Russian daily Kommersant reported, citing a source in Russia's Federal Security Service, that the Turkish nationalist group Grey Wolves linked to Daesh jihadist group and operating in many Arab countries, including Egypt, could be involved in the explosion aboard the Russian airliner.

"We do not have any information about the relationship of the Turkish organization Grey Wolves to the Russian A321 flight crash. The Interior Ministry denied last Saturday the arrest of suspects, who could have participated in the [incident] where 224 people were killed," Helmy said.

On October 31, 2015, the Russia-operated Airbus A321 crashed en route from the Egyptian resort of Sharm el-Sheikh to St. Petersburg as a result of an explosion on board. The crash has become the largest civil aviation disaster in Russian history. Daesh, which is outlawed in Russia and many other countries, claimed responsibility for the crash.

Al-Hasna area, where the Russian Airbus A321 crashed, is believed to be one of the most salient strongholds of the Ansar Beit al-Maqdis Islamist group in north of Sinai. The jihadists have pledged allegiance to Daesh terrorist organization and renamed themselves as Wilayat Sinai afterward.
