Rescue services retrieved a body of a woman from under the rubble, the statement said.
The mosque's ceiling collapsed on Saturday afternoon under a landslide. Multiple people have remained trapped under the rubble since.
Rescue teams have managed to retrieve three children from under the ruble, who were taken to a hospital, Karbala Directorate of Civil Defense chief Taher Al-Zubaidi said earlier on Sunday. Emergency services have delivered oxygen, drinking water and food to the people stuck inside the accident site by manually removing the rubble and concrete blocks.
