The US responded today to comments from the supreme leader of Iran, who called Israelis “rabid dogs” this week.

“Well, obviously we disagree with it profoundly,” Secretary of State John Kerry said before the Senate Foreign Relations Committee.

“It’s inflammatory and it’s unnecessary, and I think at this moment, when we are trying to negotiate and figure out what can and can’t be achieved, the last thing we need are names back and forth.”

Ayatollah Ali Khamenei made headlines this week for a vitriolic diatribe.

“Zionist officials cannot be called humans, they are like animals, some of them,” said Khamenei. “The Israeli regime is doomed to failure and annihilation.”

The comments, and Kerry’s response, came amid talks between the P5+1 powers and the Islamic republic to come to a deal on Iran’s nuclear program.
