A powerful Islamic State suicide blast ripped through a packed Shia mosque in Islamabad’s G-6 sector on February 6, killing at least 31 people and injuring 169 worshippers during Friday prayers—the deadliest attack in Pakistan’s capital since 2008. The explosion at Imam Bargah Qasr-e-Khadijatul Kubra, claimed by ISIS, occurred as the bomber reached the inner gate before detonating his vest. Witnesses reported gunfire moments before the blast as a volunteer tried to stop the attacker. Officials fear the death toll could rise as many victims remain critical. The attack, condemned by Pakistani leaders and the UN, underscores the resurgence of insurgencies and sectarian violence in the country, with Islamabad blaming militant sanctuaries across the Afghan border.
