Islamic State called on Muslims to launch a "holy war" against Russians and Americans over what it called their "crusaders' war" in the Middle East, an audio message distributed by supporters of the ultra hardline group said on Tuesday, according to Reuters.
"Islamic youth everywhere, ignite jihad against the Russians and the Americans in their crusaders' war against Muslims," the speech by Islamic State spokesman Abu Mohammad al-Adnani said, Reuters wrote.
The audio message also confirmed the death of Abu Mutaz Qurashi, which the SITE monitoring service said was a reference to a senior Islamic State official killed in an airstrike in Iraq in August and referred to then as Fadhil Ahmad al-Hayali.
The United States and Russia are carrying separate airstrike campaigns in Syria, which they say are targeting Islamic State.
Washington says Moscow's campaign has mainly targeted other insurgent groups including those that have fought Islamic State, a charge Russia denies.
