Survivors of Typhoon Haiyan flocked to ruined churches on Sunday, kneeling in prayer under torn roofs as the Philippines faced an enormous rebuilding task from the storm that killed at least 3,681 people and displaced 4 million.

At Santo Niño Church, near the waterfront in the flattened city of Tacloban, birds flitted between the rafters overhead as women moved through the pews with collection plates. At the end of mass, the Roman Catholic congregation broke into applause.

Rosario Capidos, 55, sat crying in one row, hugging her nine-year-old grandson, Cyrich.

Capidos had been sheltering at home with nine other members of her family when Haiyan struck on Nov. 8. As the waters rose, she floated her three grandchildren on a slab of styrofoam through a road flooded with debris and shipping containers to a nearby Chinese temple. Her family survived.
