At least three people are dead and nearly 40 homes damaged following a huge explosion Wednesday at a house in Evansville in the U.S. state of Indiana.
Authorities are worried there could be more deaths or injuries as a search mission is yet to be completed.
"There could be other victims. We have not completed our search. The buildings are not yet safe to enter," Fire Department Chief Mike Connelly told a news conference.
An investigation of the incident is underway, Connelly added, as there is no word yet on the cause of the explosion.
