"I want to remind you that our country also has various means of destruction," Putin said on Wednesday. "When the territorial integrity of our country is threatened, to protect Russia and our people, we will certainly use all the means at our disposal."

The threats have been condemned by top U.S. officials, with Sullivan saying on Sunday that the U.S. has communicated with Russia in private channels about the response America would take.
