World War Two: Thousands of bombs still left unexploded

There are potentially thousands of unexploded World War Two bombs around Wales, with emergency services still dealing with up to 20 callouts a year.

With the coastal towns of Cardiff and Swansea key German targets, many are thought to be in these areas.

At the start of the war, the authorities were “utterly unprepared” how to deal with unexploded bombs, according to historian Steve Day.

A bomb disposal officer was expected to live for two months.
