"Experts have noticed a 'surge' in pro-ISIS social media posts in the wake of Abu Bakr al-Baghdadi's death. The Counter Extremism Project said the jihadists had been posting 'regular propaganda' after the terrorist leader died in a U.S. special forces raid in Syria. While some have apparently been denying Baghdadi's death, others have pledged to fight on regardless, warning: 'Jihad will never stop, even if our own caliph dies.'  The project's director David Ibsen said ISIS would 'undoubtedly use the death of their caliph to expand their online presence'.  Speaking to The National, Mr Ibsen said: 'Official ISIS news channels have been posting regular propaganda including stories of attacks by ISIS fighters around the world and photos of captured weapons. Individuals in pro-ISIS chats on Telegram have been urging patience and warning users not to believe non-ISIS media or spread rumours. Some chatroom participants have discussed the concepts of martyrdom and perseverance, and have repledged their support to ISIS.'"
