WASHINGTON, DC: Iran allegedly threatened President Donald Trump that it would unleash sleeper cell terrorist attacks to cause havoc in the United States, just days before air strikes on the country's nuclear sites.

Insiders told NBC News that Trump received a communique from the Islamic Republic of Iran just days before he ordered US military strikes on the country's nuclear facilities, the Daily Mail reported.

Iran threatened US with sleeper cell terrorist attacks days before nuclear strikes

The official message by the regime was delivered to Donald Trump through an intermediary during the G7 Summit in Canada last week.

Interestingly, the POTUS left the G7 Summit early on June 16 to consider his options amid the conflict between Israel and Iran, insiders revealed.

Moreover, after exiting the G7 Summit, Trump told reporters aboard Air Force One that he planned to hold "early" meetings with his security team in the White House Situation Room after issuing a stunning call for people to "evacuate" Tehran amid Israeli bomb attacks there.

The US deployed B-2 bombers to drop more than a dozen "bunker busters" in Iran. Following this, Iran's foreign minister called the strikes "outrageous" and said that Tehran "reserves all options" to retaliate.

Meanwhile, after the strikes, the Department of Homeland Security issued a national terrorism bulletin on June 22 and warned of a possible cyber attack and violence, including antisemitic hate crimes, per the outlet.

The bulletin said, "The ongoing Iran conflict is causing a heightened threat environment in the United States."

The department warned that low-level cyber attacks against US networks are likely, although there are "no specific credible threats."

Furthermore, the DHS said, "Iran also has a long-standing commitment to target US Government officials it views as responsible for the death of an Iranian military commander killed in January 2020."

"The likelihood of violent extremists in the Homeland independently mobilizing to violence in response to the conflict would likely increase if Iranian leadership issued a religious ruling calling for retaliatory violence against targets in the Homeland," the department added.

Former FBI assistant director says Joe Biden’s border policy may have worsened sleeper cell risks

Former FBI assistant director Chris Swecker informed Fox News that Former President Joe Biden's border crisis may have exacerbated the condition of sleeper cells in the US. 

Swecker said, "Because of the open borders, we are at a serious catch-up phase. We don't know where those thousand Iranians are and who knows how many others got across the border."

Interestingly, more than 1,200 Iranian nationals reportedly entered the US during the Biden Administration, Trump's border czar Tom Homan revealed.

Meanwhile, Swecker added that during Biden's tenure, the FBI focused on homegrown terrorists and lost track of foreign threats, according to the outlet.

"There's a certain population of Iranians in the US that we know about, but there's thousands and thousands that we don't know about because of the open border situation," the former FBI assistant director said.

He added, "The Bureau was concentrating their resources on so-called domestic terrorists like white supremacists and right-wing extremists, and calling them the most serious terrorist threat to this country when it was the international terrorists that should have been the focus of the bureau's efforts."
