West Palm Beach (US) | US President Donald Trump on Saturday acknowledged that the operations against Iran may lead to American casualties.

"The lives of courageous American heroes may be lost, and we may have casualties," he said in a video posted to social media early Saturday morning. "That often happens in war."

After the June attacks on Iran's nuclear sites, Trump said, "We warned them never to resume their malicious pursuit of nuclear weapons. And we sought repeatedly to make a deal. We tried."

He added that Iran "rejected every opportunity to renounce their nuclear ambitions, and we can't take it anymore."

Trump called the attacks on Iran "a noble mission," saying they were necessary because of Iran's pursuit of nuclear weapons and missile systems that could reach the US.

He called on Iranian people to take over the government.
