Is there a credible explanation for a liquid-filled mortar shell other than WMD dispersal? Perhaps these were training rounds?

Training rounds is a possibility, but why bury those? Notice that the story did not say there was no WMD involved, just no chemicals. Biological agents are not usually referred to as chemicals. Who knows?

You generally wouldn't use bioweapons in 120mm mortars.

Heck, seems this was near a river, possible water simply seeped into corroded shells and sat there.

Anyway, hope no FReepers ran around gloating over this to to any left-wing friends or coworkers last week.
