Russian volunteers are searching former World War II battlefields for the remains of soldiers who are listed as "missing in action" to give them a proper burial.

An estimated 70 million people were killed during World War II and more than a third were lost on the Russian front. Four million are still missing.

But with winter on its way, the annual search for the dead must be abandoned until spring.

Al Jazeera's Peter Sharp reports from St Petersburg, where some of the worst fighting took place.
