A recording released online, purportedly from ISIS spokesman Abu Mohammed al-Adnani, has called for further attacks against the West.
The recording urges followers to carry out attacks during the Muslim holy month of Ramadan, which begins in early June.
The roughly half-hour message in Arabic acknowledges losses against the anti-ISIS coalition but asserted the jihadist group would prevail in the long run.
The call comes after ISIS-inspired attacks on Western targets, from Brussels to San Bernardino, have shown the reach and influence of the jihadist group.
The message was released two days after EgyptAir Flight 804 crashed in the Mediterranean, but Adnani’s recording makes no reference to the tragedy.
