U.S. President Donald Trump on Thursday threatened again to strike Iran "very hard" if its authorities "start killing people" protesting in the Middle Eastern country.
"I have let them know that if they start killing people ... we are going to hit them very hard," Trump said in an interview with a conservative radio.
The U.S. president and other senior U.S. officials recently warned on several occasions that the U.S. would act if Iran "kills peaceful protesters."
On Wednesday, Iran's Foreign Ministry condemned what it described as "interventionist and deceptive" remarks by the Trump administration on recent unrest in the country, saying they reflected the U.S. continued hostility toward the Iranian people.
The U.S. comments on Iran's internal affairs were part of a long-standing policy of pressure and interference, rather than genuine concern for the welfare of Iranians, said the ministry in a statement.
Protests have erupted in several Iranian cities since late last month over the sharp fall in the rial and long-standing economic hardships. Iranian authorities have acknowledged the demonstrations and said they are willing to address economic grievances, while warning against violence, vandalism and unrest.
Dozens of people, including protesters and members of the security forces, have been killed since the protests began, according to various reports. There is no official figure for the death toll.
