The Russian Foreign Ministry has taken a jab at its U.S. counterpart by uploading a picture of U.S. Secretary of State John Kerry and his predecessors "digging out trenches of the Cold War."
The loaded comment was made alongside a picture of the politicians holding spades at a construction site, taken last Thursday at a ceremony for a future museum at the U.S. Diplomacy Center in Washington.
"Let's hope that this is not the mobilization of veterans on digging out trenches of the Cold War," the Russian Foreign Ministry said Monday on its Facebook account.
Also pictured in the photograph are former state secretaries Hillary Clinton, Colin Powell, Henry Kissinger, James Baker and Madeleine Albright.
The post drew more than 2,300 likes and had been shared more than 800 times as of Tuesday afternoon.
"They are burying the corpses of those who have died as a result of their policies," one user wrote on Facebook.
"Digging their own graves?" wrote another user.
The ministry's comment is the latest in a war of words that it appears to be waging via its social media accounts.
Last week, it asked Facebook users to give U.S. President Barack Obama a history lesson after he hinted Russia was trying to reclaim territories that it lost during the 19th century.
Meanwhile at the end of August, it responded to a jibe from Canada's NATO delegation by tweeting a map of Crimea labelled as Russia with the words: "Helping our Canadian colleagues to catch up with contemporary geography of Europe."
But for some Facebook users followers, the latest post took the gag one step too far.
"Are you serious? Is this an official account?" asked one bewildered user.
