It was an unusual email to receive from the White House, but these are unusual times.
The statement contained details of what was discussed at a meeting between the US President Joe Biden and his national security team.
Normally, such briefings are classified, but on Friday, the White House decided to share the stark warnings that Mr Biden was receiving from his staff.
"They advised the President and Vice President that another terror attack in Kabul is likely, but that they are taking maximum force protection measures at the Kabul Airport," the statement read.
"The next few days of this mission will be the most dangerous period to date," the US President was also told by advisers.
Asked about the statement, the White House Press Secretary Jen Psaki said the administration felt it was important to be open with the public about the threats facing US forces in Afghanistan.
"That threat is acute, it is ongoing. Our troops are still in danger and they are taking the steps they are taking to save lives and evacuate people because of their commitment to the mission, and we felt it was important for people to understand that," she said.
Earlier, the US President had once again defended the evacuation mission and also paid tribute to the US service members who were killed at Kabul Airport.
"The mission being performed is dangerous, and it has is now come with a significant loss of American personnel. But it's a worthy mission because they continue to evacuate folks out of that region," he said.
Thursday became the worst day of Joe Biden's presidency so far, as the Pentagon confirmed the biggest single loss of US service members in a decade.
It was the nightmare scenario for the White House.
If the administration was banking on a peaceful evacuation effort to help ease some of the political pressure on Mr Biden, those hopes were dashed when American lives were lost.
Republicans have ramped up their criticism of the president, with some calling for him to resign or face impeachment.
The top Republican in the House of Representatives, Minority Leader Kevin McCarthy, said that for now he was focused on evacuations rather than impeachment but he warned that there would be a "day of reckoning" for Joe Biden, saying that he had lost the trust, faith and confidence of the American public.
Weapons and equipment have been left behind in Afghanistan and are now in enemy hands. There is also outrage following reports that the US gave the Taliban a list of names of American citizens and Afghan allies in order to facilitate their evacuation.
"Basically, they just put all those Afghans on a kill list," a US defence official told Politico.
"It's just appalling and shocking and makes you feel unclean," the official said.
Last night, the Taliban said it was starting to take control of Kabul Airport.
The claims were quickly denied by the White House and the Pentagon but it was a stark reminder that the last piece of Afghanistan controlled by the US will soon be handed back.
Joe Biden vowed to bring US troops home and end a conflict that has claimed so many lives, but as America's longest war enters its final days, the danger faced by those on the frontlines has never been greater.
