US President Donald Trump has said that the United States has begun “major combat operations” in Iran, warning that there may be US casualties, Reuters reports.

“My administration has taken every possible step to minimise the risk to US personnel in the region. Even so, and I do not make this statement lightly, the Iranian regime seeks to kill,” Trump said in a video shared on Truth Social.

“The lives of courageous American heroes may be lost, and we may have casualties that often happens in war, but we’re doing this, not for now. We’re doing this for the future, and it is a noble mission.”
