Archaeologists have unveiled two Iron Age "bog bodies" which were found in the Republic of Ireland. The bodies, which are both male and have been dated to more than 2,000 years old, probably belong to the victims of a ritual sacrifice.

In common with other bog bodies, they show signs of having been tortured before their deaths.

Details of the finds are outlined in a BBC Timewatch documentary to be screened on 20 January.

Hundreds of bodies have been recovered from peat wetlands across Northern Europe. The earliest accounts date back to the 18th Century. The unique chemistry of peat bogs essentially mummifies bodies.
