ISLAMABAD: Pakistani authorities have taken into custody Sultan Aziz Azzam, a senior member of Daesh who used to oversee the banned outfit’s media operations and headed its “Al Azzam” outlet, state media reported on Thursday. 

The state-run Pakistan TV Digital reported that Azzam was a senior member of Daesh regional affiliate ISKP, who hails from Afghanistan’s Nangarhar province and is a graduate of the University of Nangarhar where he studied Islamic jurisprudence. 

The state media said he joined ISKP in 2016 and later became a prominent member of its leadership council.

“He was arrested in May 2025 while attempting to cross from Afghanistan into Pakistan,” Pakistan TV Digital reported, citing intelligence sources. 

In November 2021, Washington listed Azzam as a “Specially Designated Global Terrorist” (SDGT). The move bars American citizens from engaging in transactions with persons designated as SDGTs. 

According to a report on the UN Security Council’s website, Azzam has played an “instrumental role” in spreading Daesh’s violent ideology, glorifying and justifying “terrorist acts.” 

“Building on his former experience as an Afghan journalist, his activity as ISIL-K’s spokesperson has increased ISIL-K’s visibility and influence among its followers,” the report states. 

The report further states Azzam claimed responsibility on behalf of Daesh for the suicide attack near Hamid Karzai International Airport on Aug. 26, 2021, which killed at least 170 Afghans and 13 US service members and injured 150 more. 

The development takes place amid tense relations between Pakistan and Afghanistan, with Islamabad alleging militants use Afghan soil to carry out attacks against Pakistan. Kabul denies the allegations. 

Tensions surged in October when Pakistan and Afghanistan engaged in fierce border clashes, claiming to have killed dozens of soldiers of the other side. 

Pakistan has urged the Afghan Taliban-led government to take “decisive action” against militants it says operate from its soil. Afghanistan says it cannot be held responsible for Pakistan’s security challenges.
