A deadly explosion struck a mosque in Islamabad during crowded Friday prayers, killing at least 31 people and injuring 169 others, according to officials.

Authorities said the attacker was stopped at the mosque entrance before detonating explosives, causing devastation among worshippers gathered inside.

Rescue teams, police officers, and local residents rushed to the scene, carrying the wounded to ambulances and private vehicles for transport to nearby hospitals.

Medical centers across the capital quickly filled with injured adults and children, while anxious relatives gathered outside emergency wards searching for information about loved ones.

Officials reported that several victims remained in critical condition as emergency crews continued rescue efforts and secured the area.

Pakistan’s leaders strongly condemned the attack, calling it an inhumane act aimed at innocent civilians.

Prime Minister Shehbaz Sharif and President Asif Ali Zardari expressed deep sorrow and instructed authorities to provide the best possible medical care to survivors.

No group immediately claimed responsibility, but the attack has renewed concerns about rising militant violence and the vulnerability of places of worship, underscoring calls for stronger security and national unity.
