A five-storey block of flats has collapsed and families feared are trapped in the rubble.

Witnesses say there was no explosion but a train had just passed on tracks close by. Images from the scene in Naples, Italy, show firefighters at the scene frantically searching for survivors, with the interior of a number of apartments visible. It is feared families are trapped underneath the rubble, although no casualties have yet been reported.

A resident who lives nearby told local media: “I heard the sound of the building collapsing. Freight trains pass below and someone told me that he had heard that shortly before the collapse one had passed.” According to local media the building was undergoing reconstruction work, said to have been on the first floor. Locals are also on the scene digging up rubble to assist the search for those feared missing.
