A suicide bomb attack at the Imam Bargah Qasr-e-Khadijatul Kubra Shia mosque on the outskirts of Islamabad on Friday killed at least 31 people and wounded over 170. The explosion occurred after Friday prayers, and police said the death toll was "expected to rise." A security source explained, "The attacker was stopped at the gate and detonated himself." No group has claimed responsibility yet. Pakistan's Defence Minister Khawaja Asif tweeted that the bomber had traveled to Afghanistan and blamed India for sponsoring the attack, though no proof was provided. India’s Ministry of External Affairs called the accusation "baseless" and said it was unfortunate Pakistan blames others instead of fixing its own problems. Eyewitness Muhammad Kazim described the moment: "During the first bow of namaz, we heard gunfire. And while we were still in the bowing position, an explosion occurred." South Asia analyst Michael Kugelman suggested on social media that the attack likely involved either the local Islamic State affiliate or anti-Shia militants. At the nearby Pakistan Institute of Medical Sciences hospital, injured people, including children, arrived on stretchers and in vehicles. Some victims had blood-soaked clothes, and relatives cried at the emergency ward. Security forces secured the mosque area, where pools of blood and scattered belongings marked the scene of the blast. The attack comes amid ongoing conflicts with insurgent groups in Pakistan’s border regions with Afghanistan. Shias constitute 10-15% of Pakistan’s mainly Sunni population and have faced past attacks. Islamabad accuses separatist and Islamist militants of using Afghanistan as a base for strikes, claims dismissed by the Afghan Taliban government. Tensions have risen along the Pakistan-Afghanistan border.
