Isis militants released an audio message repeating their claim to have brought down the Russian jet which crashed on Saturday and caused the death of hundreds Russian tourists and crew.

They also challenge the Egyptian authorities to “prove we did not”.
Wilayat Sinai (Sinai Province) said they would reveal the way they did it soon in a recording entitled: “We downed it, so die in your rage”.

Experts have questioned the fact that ISIS has claimed responsibility once more without providing actual proof, while the Egyptian President Abdel Fattah al-Sisi described such claims as “propaganda”.
