Developing Story: A deadly suicide bombing struck Imambargah Khadijat-ul-Kubra in Tarlai, a suburban area of Pakistan’s capital, on Friday, leaving more than 30 worshippers martyred and over 90 injured, several of them critically, according to hospital and police sources.

The attack occurred during Friday prayers, when the imambargah was packed with worshippers, significantly increasing the number of casualties. Initial reports suggested the blast took place near the entrance of the imambargah, killing at least 12 people, but subsequent assessments by law enforcement and rescue authorities raised the death toll to over 30 as some of the injured succumbed to their wounds. This is second biggest suicide attack in Islamabad in last three months as first was at Islamabad District Courts G-11.
Police officials said the suicide bomber was intercepted at the gate of the imambargah by security personnel or volunteers. Moments later, the attacker detonated the explosive device, causing widespread devastation in the surrounding area. The impact shattered nearby structures, damaged vehicles, and spread panic among worshippers.
Emergency responders, police, Rangers, and other security agencies swiftly reached the site, cordoned off the area, and launched a search and clearance operation to rule out the presence of any additional attackers or explosive devices. Bomb disposal squads later declared the area cleared.
The injured were rushed to nearby hospitals in Islamabad and Rawalpindi, where doctors imposed an emergency. Hospital officials confirmed that several victims remain in critical condition, raising fears that the death toll could rise further.
Blood donation appeals were issued, and medical staff worked round the clock to treat the wounded.
According to initial police investigations, the attacker was allegedly affiliated with Fitna al-Khawarij, a term used by Pakistani authorities for extremist militant groups. Law enforcement agencies have begun a forensic analysis, including examination of the bomber’s remains, explosive material, and CCTV footage from the area, to trace facilitators and planners of the attack.
Police sources stressed that targeting mosques and worshippers has no connection with the teachings of Islam, calling the attack an act of pure terrorism aimed at spreading fear and sectarian hatred.
The Tarlai bombing marks the third major attack on imambargahs in the Rawalpindi–Islamabad region over the past two decades. Previous attacks include:
Imambargah Qadeemi, Raja Bazaar, Rawalpindi on 28 December 2009, which left 38 dead and over 80 injured.
Raja Bazaar blast near Imambargah Yadgar-e-Hussaini on 10 January 2013, killing 25 people.
In Islamabad, I-8 Markaz Imambargah was attacked on 20 November 2015.
The attack took place on a day when the President of Uzbekistan was present in Islamabad on an official visit. Notably, a day earlier, terrorists carried out attacks at 12 locations in Balochistan when the President of Kazakhstan was due to arrive in the capital. Analysts and security officials say these incidents cannot be viewed in isolation, but rather as part of a coordinated messaging campaign by militant groups to project Pakistan as unsafe and to undermine its internal security and international engagements.
Officials have also pointed to the regional security environment, noting Pakistan’s proximity to Afghanistan and the continued threat posed by militant networks operating across borders.
Federal and provincial authorities strongly condemned the attack, expressing condolences to the families of the victims and prayers for the speedy recovery of the injured. Security across Islamabad and Rawalpindi was further tightened, particularly around religious places, sensitive installations, and routes linked to foreign dignitaries.
Authorities reiterated their resolve to bring the perpetrators and their facilitators to justice, vowing that such attacks would not weaken Pakistan’s commitment to counterterrorism or its efforts to ensure the safety of citizens and international guests.
Investigations are ongoing.
