The Islamic State (ISIS) has declared a new “global offensive” against Europe and Israel while the rest of the world is distracted by the ongoing crisis in Ukraine.

The message, entitled “Fight them, and God will chastise them at your hands,” which was timed to release during the sacred Muslim month of Ramadan, called for jihadist followers to avenge the death of ISIS former leader, Abu Ibrahim al Hashimi al Qurashi. Abu Ibrahim was killed in a United States special forces raid in February.

In a speech leaked online, the group’s new spokesperson Abu-Omar al-Muhajir told their followers to take advantage of Russia’s invasion and stage terror attacks while “the crusaders are fighting each other.”

“We announce, relying on God, a blessed campaign to take revenge,” al-Muhajir said in an audio clip retrieved from the Telegram messaging platform. “Fight them all and Allah will answer and punish them at your hands.”
