The warning came as US forces in Iraq were on alert for possible reprisal attacks war planes targeted the Kataib Hezbollah militia group on Sunday night in an escalation of tensions.
A military officer told the Reuters news agency: “I think they will retaliate.”
The founder of the militia – who is closely aligned with Iran – vowed revenge.
“The blood of the martyrs will not be in vain and our response will be very tough on the American forces in Iraq,” Jamal Jaafar Ibrahimi, who is known by his nom de guerre Abu Mahdi al Mohandes, said in a statement.
Iraqi embattled government condemned the US action against the state-approved militia group in western Iraq on Sunday as a “flagrant violation” of its sovereignty.

Concerns are growing that Iraq will become a new battleground for Tehran and Washington to wage a proxy war
In a statement from his office, Prime Minister Adel Abdul Mehdi “described the American attack on the Iraqi armed forces as an unacceptable vicious assault that will have dangerous consequences.”

US Assistant Secretary of State David Schenker said the Sunday strikes on were a message to Iran after months of “restraint” by the US administration.
“We thought it important to hit a significant target set to send a very clear message to them about how serious we take American lives, “Mr Schenker told reporters in a telephone conference.
” This was a response that was serious, but was, I think in many ways, proportionate, “he said. “We don’t want an escalation here, we want a de-escalation.”
Brian Hook, the US envoy on Iran, said Washington had held back from responding despite a series of attacks tied to Tehran-linked militias.
President Donald Trump “has been very patient. He has shown a great deal of restraint,” Mr Hook said in the same briefing.
“We very much hoped that Iran would not miscalculate and confuse our restraint for weakness. But after so many attacks, it was important for the president to direct our armed forces to respond in a way that the Iranian regime will understand. “
” We will not tolerate attacks against US citizens, our military or our partners and allies in the region, “Mr Hook added.
The Sunday night airstrikes are said to have killed at least 25 militia fighters, according to Iraqi sources.

“What we did was take a decisive response that makes clear what President Trump has said for months and months and months, which is that we will not stand for the Islamic Republic of Iran to take actions that put American men and women in jeopardy, “he told reporters.
Iran has denied any involvement in such attacks.
“We strongly deny any role in the attack on American forces. This claim without any evidence cannot justify bombing and killing people in violation of international law, “said Iranian government spokesman Ali Rabiei, quoted by the semi-official news agency Fars.
