"There was one police officer who literally threw two people over his shoulders and ran" with them towards medical staff, he said. Several people were trapped in the basement of the collapsed building but were rescued, Dippolito said."We're still in rescue mode. We have not transitioned into a recovery mode," he said.Emergency crews were still working to rescue people who may be stuck in the building, the fire chief said.Governor Josh Shapiro said the exact number of injuries was not yet known, and the cause of the blast remained under investigation.Images and videos posted on social platforms by local media outlets show a partially collapsed building with massive flames billowing out of it.Shapiro praised the support from authorities around the region who rushed to offer assistance, and said that the residents living near the nursing home were "outstanding".
