Breaking: Downing of Russian airplane, killing of more than 220 Russian crusaders on board. Soldiers of the Caliphate were able to bring down a Russian plane above Sinai Province with at least 220 Russian crusaders aboard. They were all killed, praise be to God. O Russians, you and your allies take note that you are not safe in Muslims lands or their skies. The killing of dozens daily in Syria with bombs from your planes will bring woe to you. Just as you are killing others, you too will be killed, God willing.'
