IS controlled large parts of Syria and Iraq where they declared a caliphate in June 2014. Over the years they lost of the land and were defeated in Iraq in 2017 and two years later in Syria.
In one of their deadliest in a year, IS sleeper cells attacked workers collecting truffles near the central town of Sukhna in February, killing at least 53 people — mostly workers but also some Syrian government security forces.
Experts who follow Jihadi groups say it is too early to say if the new spate of attacks marks a new resurgence by the extremists that ruled millions of people in Syria and Iraq with terror.
Last week, IS announced the death in Syria of its little-known leader, Abu al-Hussein al-Husseini al-Qurayshi — who headed the extremist organization since November — and named his successor. He was the fourth to be killed since its founder Abu Bakr al-Baghdadi was killed in 2019 by US troops in northwest Syria.
