FRANKFURT, Germany — Three people, including a 10-month-old girl, were killed Sunday when high winds toppled a tree in northern Germany during an Easter egg hunt, police said.

Around 50 people from a nearby residential facility for new mothers, pregnant women and children were attending the event in woods near the town of Satrupholm at about 11 a.m. when a 30-meter (100-foot) tree fell on the group, police said in a statement.

Four people were pinned under the tree. A 21-year-old woman and a 16-year-old girl were treated by first responders but died at the scene, while the woman’s 10-month old daughter died later in the hospital. An 18-year-old woman suffered serious injuries and was brought to the hospital by helicopter.

The facility is part of the state-funded child welfare system and supports pregnant women and new mothers who need help, according to its website. Grief counselors were sent to the scene.

Pictures from the scene published by the Bild news site showed several Easter eggs scattered on the ground and two of the victims covered in white sheets.

The area had been under a high winds warning from the German weather service.
