A fourth person was confirmed dead and three people remained unaccounted for, two days after an explosion at a chocolate factory shook a small town in Pennsylvania in the US.

West Reading Borough chief of police Wayne Holben confirmed that the body of a fourth victim had been found under debris early on Sunday at the RM Palmer plant in the borough of West Reading, about 60 miles (96km) northwest of Philadelphia.
