President Vladimir Putin said on Monday Russian air strikes in Syria would last as long as was necessary to punish those guilty of blowing up a Russian airliner over Egypt last month, an incident in which 224 people were killed.
The Islamic State militant group (ISIS) claimed Wednesday that it planted "the bomb that downed the Russian airliner Airbus A-321" over Sinai last month.
ISIS also claimed they downed the Russian plane due to “Russia’s rash arrogant decision” to participate directly with its own air force in the war against the "Muslims of Al-Sham," in Syria, starting 30 September 2015.
The Kremlin said last week that a bomb had ripped apart a Russian passenger jet over Egypt last month and promised to hunt down those responsible and intensify its air strikes on Islamist militants in Syria in response.
Egypt has opened an investigation into the causes of the crash, and allowed Russia to take part in the probe that is still underway.
