The Russian ambassador to the UK, Alexander Yakovenko, is being mocked for publishing a picture of a "terrorist," without realizing it was from a scene in a comedy movie.

Yakovenko wrote a message on his personal Twitter account criticizing the US's comments on Russian involvement in Iraq, along with a picture of a presumably ISIS member in a beard and turban.

Actor and former White House official Kal Penn responded with a tweet noting that it is a picture of him, from a scene in the movie Harold & Kumar Escape from Guantanamo Bay."
