Hampshire police have confirmed that they have discovered two guns, ammunition and two home made incendiary devices in a forest on the Isle of Wight.
The items were found by a dog walker in Parkhurst Forest on Friday 24th August.
The South East Counter Terrorism Unit is investigating the finds which were hidden in the forest for several years.
Officers say one line of enquiry is that the weapons are related to IRA prisoners who were held in the Island's jails during the 1970s and 80s.
The police say they don't believe the finds relate to any current criminal activity.
