Israeli Prime Minister Benjamin Netanyahu waded into the clash between Mexico and the United States on Saturday, tweeting out his opinion on the efficacy of walls.
Israel has also built a wall dividing the West Bank from East Jerusalem.
It didn't take long for Mexico's foreign ministry to blast out a statement saying that it was far less than pleased to have read Netanyahu's tweet.
"The Mexican Foreign Ministry told the Israeli government, through its Ambassador to Mexico, its deepest dismay, rejection and disappointment over Prime Minister Netanyahu's Twitter message regarding the construction of a border wall," the statement read. "Mexico is a friend of Israel, and must be treated as such by its Prime Minister."
A senior Israeli official told Israeli newspaper Haaretz that Mexico was "enraged by the statement" that Israel had put out.
