Iranian President Hassan Rouhani said on Monday nobody should threaten his nation, responding to a tweet from U.S. President Donald Trump in which he threatened to strike 52 sites in Iran.

"Those who refer to the number 52 should also remember the number 290. #IR655," Rouhani tweeted, referring to the 1988 shooting down of an Iranian airline by a U.S. warship in which 290 were killed. "Never threaten the Iranian nation."
