Tragic Suicide Bombing at Islamabad’s Khadija Tul Kubra Shia Mosque Claims 31 Lives, ISIS Takes Responsibility
A devastating suicide bombing struck the Khadija Tul Kubra Shia mosque (also known as Imam Bargah Qasr-e-Khadijatul Kubra) in Islamabad’s Tarlai Kalan area on Friday, February 6, 2026, during crowded Friday prayers, killing at least 31 people and injuring more than 169 others. The attack, claimed by the Islamic State group (ISIS), marks the deadliest terrorist incident in Pakistan’s capital in nearly two decades—since the 2008 Marriott Hotel bombing that killed over 60—and has heightened fears of resurgent sectarian violence and the spread of extremist threats beyond the country’s border regions.
The explosion occurred as worshippers gathered for midday prayers at the mosque on the southeastern outskirts of Islamabad. According to police and security sources, the attacker approached the entrance, was stopped at the gate by security personnel, and detonated an explosive vest laden with powerful explosives. The blast caused widespread destruction inside the mosque compound, scattering debris, shattering windows, and leaving bloodied bodies amid the chaos. Eyewitness accounts and verified social media footage described scenes of horror: panicked survivors fleeing, rescuers pulling injured from the rubble, and the air thick with smoke and cries for help.
“The attacker was halted at the gate and detonated himself,” a senior security official told reporters. Hospital officials at the Pakistan Institute of Medical Sciences (PIMS) and other facilities reported treating scores with shrapnel wounds, burns, and severe trauma. By Saturday morning, February 7, the death toll stood at 31, with authorities warning it could rise as some critically injured remain in intensive care.
The Islamic State group swiftly claimed responsibility through its Amaq News Agency and Telegram channels. In a statement monitored by SITE Intelligence Group, ISIS described the bomber as a “martyrdom-seeker” who targeted the Shia congregation, detonating his vest to “inflict a large number of deaths and injuries.” The group released an image purporting to show the attacker holding a weapon, his face obscured. ISIS has a long history of sectarian attacks against Shia Muslims, whom it views as apostates, and its regional affiliate—often linked to ISIS-Khorasan (ISIS-K)—has carried out similar operations in Pakistan and Afghanistan.
Pakistan’s military and intelligence agencies responded quickly. By Saturday, authorities announced the arrest of four individuals described as “facilitators” who allegedly aided the bomber. Security sources claimed a major breakthrough with the detention of an Afghan national identified as the alleged mastermind behind the plot, though details remain limited pending investigation. The military emphasized that the attack bore hallmarks of cross-border involvement, sharpening focus on militant networks operating from Afghanistan.
The bombing is the second significant attack in Islamabad in recent months, following a November 2025 incident that killed 12. It underscores growing concerns that extremist groups are extending their reach into urban centers far from traditional strongholds in Khyber Pakhtunkhwa and Balochistan. Pakistan has faced waves of sectarian violence in the past, particularly against its Shia minority (estimated at 10-15% of the population), with groups like Lashkar-e-Jhangvi and Sipah-e-Sahaba historically responsible. However, ISIS’s involvement highlights the evolving threat from transnational jihadist networks exploiting local grievances.
International condemnation was swift. UN Secretary-General António Guterres strongly denounced the attack, calling for justice and solidarity against terrorism. Leaders from the United States, European Union, and neighboring countries expressed condolences, with many stressing the need for enhanced counterterrorism cooperation. In Pakistan, political figures across parties united in grief, with Prime Minister Shehbaz Sharif vowing to root out terrorism and protect religious minorities.
On Saturday, February 7, thousands of mourners gathered under heavy security at the same mosque for funeral prayers and burials. Coffins draped in green and black were carried through streets, with families weeping as they laid loved ones to rest. Community leaders called for calm and unity, urging authorities to prevent reprisals amid fears of heightened sectarian tensions.
The attack has reignited debates over Pakistan’s security strategy. Critics argue that despite military operations against militants, intelligence failures and porous borders allow groups like ISIS to regroup and strike soft targets. Shia organizations have long demanded better protection for mosques and processions, especially during religious observances.
As Islamabad tightens security and the investigation continues, this tragedy serves as a grim reminder of the persistent threat of terrorism in Pakistan. The loss of innocent lives during a sacred moment of worship has left a nation mourning—and determined to confront the forces of extremism that continue to claim victims in the name of ideology.
Our thoughts remain with the victims, their families, and the Shia community in Pakistan during this time of profound sorrow.
