Georgia apartment explosion: Four injured, crews make sure surrounding homes are safe

An explosion at a Georgia apartment complex left four people injured on Sunday afternoon and it's believed to have been caused by some sort of gas line issue. Crews are working to assess the stability of the building and shore it up to allow rescue workers to search inside. Fire investigators said at least three apartments were destroyed in the blast and caused a partial collapse of the building. Officials are using drones to help assess the damage.
