OTTAWA (Reuters) - Canada said on Wednesday it intercepted gun parts sent into the country through international mail, leading authorities to seize "ghost guns" and related 3-D printing equipment from two locations in British Columbia.

Ghost guns are privately made firearms that are not marked with a serial number and are difficult for law enforcement to trace.
