The Chicago home of the brother of Pope Leo XIV was hit with a bomb threat amid the pontiff's ongoing feud with President Trump. 

John Prevost, the brother of the papal leader Robert Prevost, had his home in the Chicago suburb of New Lenox targeted by a bomb threat on Wednesday evening. 

Police said officers were called to Prevost's home around 6:30pm and secured a perimeter around the property, reports NBC5. 

Neighbors were ordered to evacuate their homes as officers scoured the residence, with bomb sniffing K9 units also dispatched to the scene. 

Police eventually determined the threat was unsubstantiated and no explosive devices were found. 

New Lenox police said in a statement the investigation remains open to 'determine the origin of the report', warning that making false reports of this nature 'is a serious offense and may result in criminal charges.' 

The bomb threat comes amid the feud between Pope Leo XIV and Trump over the war with Iran, which the Vatican leader has sharply criticized in recent weeks. 

After the Pope condemned the rhetoric from the White House and called for peace earlier this week, Trump issued a scathing Truth Social rant branding the pontiff 'weak on crime.' 

The Pope's brothers previously made headlines when Prevost was unveiled as the new pontiff last year, as they said they were stunned to see their sibling emerge at the Vatican following a Conclave watched around the world. 

And while John Prevost's home was targeted by a bomb threat this week amid the Pope's spat with Trump, his other brother Louis has made no secret that he is a fan of the president. 

Louis Prevost was invited to the White House by Trump after his brother became the Vatican leader, as the White House appeared intent on fostering a relationship with the first ever American Pope. 

Soon after, Louis's old social media tirades emerged, showing his anti-woke takes on social issues and branding supporters of Joe Biden 'mentally afflicted.' 

The White House's attempts to woo the Prevost family have been curbed in recent weeks following the Pope's criticism of the war with Iran. 

Last week he condemned the President over his threats against the country, when he warned that 'a whole civilisation will die tonight, never to be brought back again'.

The Pope called it a 'truly unacceptable' statement.

And on a trip to the African nation of Cameroon this week, the Pope made a thinly veiled dig at Trump as he said the world is being 'ravaged by a handful of tyrants.' 

Without citing Trump by name, Pope Leo decried leaders who use religious language to justify wars and urged a 'decisive change of course'. 

He condemned 'an endless cycle of destabilisation and death' on a visit to Bamenda, a 'bloodstained' region of Cameroon which has been gripped by a separatist insurgency for nearly a decade.

'Those who rob your land of its resources generally invest much of the profit in weapons, thus perpetuating an endless cycle of destabilisation and death,' the US-born pontiff said in a speech at Saint Joseph's Cathedral.

He added: 'The masters of war pretend not to know that it takes only a moment to destroy, yet often a lifetime is not enough to rebuild.

'They turn a blind eye to the fact that billions of dollars are spent on killing and devastation, yet the resources needed for healing, education and restoration are nowhere to be found.'

The pointed sermon followed Trump's stunning Truth Social post on Sunday, where he branded the pontiff 'a very liberal person' who is 'WEAK on Crime, and terrible for Foreign Policy'.

He also said that Leo, 70, was only made Pope 'because he was an American', and 'If I wasn't in the White House , Leo wouldn't be in the Vatican.'

He added: 'I don't think he's doing a very good job. He likes crime I guess.

'We don't like a pope who says it's ok to have a nuclear weapon. We don't want a pope that says crime is ok. I am not a fan of Pope Leo.'

Trump then sparked further controversy by posting an AI-generated image seemingly depicting himself as Jesus Christ, triggering backlash even among his usual supporters.
