A BOMB disposal team had to be called to Monifieth on Monday after a report of a suspicious item on the beach.
The discovery was made by a member of the public who alerted Tayside Police at around 1.45 p.m.
Both the police and HM Coastguard attended the scene and after a search of the area, a second device was found nearby.
The Northern Diving Group of the Royal Navy Explosive Ordinance Disposal were called to make the devices safe.
Both were saturated in sea water before controlled explosions were carried out. It was found that the items were a British air dropped parachute illuminator and a World War One charge case, which fits inside a sea mine.
A police spokesperson said although these types of incidents are uncommon members of the public should be vigilant.
He explained: “Whilst incidents such as this are rare, Tayside Police would like to reiterate the message that members of the public should not touch suspicious items found on the beach.
“The correct course of action was carried out in this case whereby the member of the public informed the police so that the necessary experts could be contacted.”
