At least five people were killed and 10 others injured when the makeshift roof of an under-construction mosque collapsed during Friday congregational prayers in Karachi.
Several others, including children, are feared buried beneath the rubble at Masjid Usman Ghani in Block H of the North Nazimabad neighbourhood.
The injured have been taken to Ziauddin Hospital and Abbasi Shaheed Hospital. Four are in critical condition.
Eye witnesses said the structure that fell was a makeshift extension to the roof, which was erected to protect worshippers from the scorching heat during day-time prayers. Ceiling fans were also attached to the extension that collapsed, they added.
So far, it is not clear what caused the incident.
Station House Officer (SHO) Hyderi Zulfiqar Hyder said the roof collapsed as the main prayer ended and people were offering supplementary Sunnah prayers.
The mosque was more crowded than usual due to first Friday of Ramazan.
