Four unknown soldiers killed during the First World War have been buried with full military honours.
One unknown soldier of the Machine Gun Corps (MGC) and three unknown soldiers of unknown regiments were laid to rest at the Commonwealth War Graves Commission (CWGC) Loos British Cemetery, France.
The service was conducted by the Reverend Stephen Pratt CF, Chaplain to the Royal Tank Regiment (RTR).
The RTR provided both the bearer and firing party for the ceremony.
Nicola Nash from the Ministry of Defence's Joint Casualty and Compassionate Centre (JCCC) said:
"It’s a great honour to be here today to lay these brave men to rest, who fought so courageously alongside their comrades.
"Although we have not been able to identify them, they were still buried with the dignity and respect that they deserved."
The soldiers' remains were discovered during building work in the Vendin-le-Vieil area of northern France in December 2016.
Two MGC shoulder titles and a cap badge were found along with the soldiers, plus numerous items of British Army kit.
The heavy branch of the MGC was the first to use tanks in combat during the Battle of the Somme and was subsequently amalgamated into the Tank Corps, later known as the RTR.
Warrant Officer (WO1) Harley Upham, Royal Tank Regiment said:
“I am deeply honoured and moved to have been here today."
