President Joe Biden has urged Americans to reject political violence and recommit themselves to resolving their differences peacefully, saying the upcoming presidential election will be a "time of testing" in the aftermath of the attempted assassination of former President Donald Trump.

In a prime-time national address Sunday from the Oval Office, Biden said political passions can run high but "we must never descend into violence." The president said his party and the Republicans can compete forcefully over different policy visions — but must do it in a civil fashion.

World leaders reacted with shock to the wounding of Donald Trump in an assassination attempt against the former U.S. president at an election rally.

Donald Trump narrowly escaped an assassination attempt at a political rally Saturday, leaving the FBI hunting for information about how a gunman could attack a former U.S. president.

Former President Donald Trump was the target of an assassination attempt Saturday at a Pennsylvania rally, days before he was to accept the Republican nomination for a third time. A barrage of gunfire set off panic, and a bloodied Trump, who said he was shot in the ear, was surrounded by Secret Service and hurried to his SUV as he pumped his fist in a show of defiance.

Trump's campaign said the presumptive GOP nominee was doing "fine" after the shooting, which he said pierced the upper part of his right ear.

Hungarian Prime Minister Viktor Orbán has made a Trumpian vow to "Make Europe Great Again" during his country's six-month presidency of the European Union.

The EU's longest-serving leader — who has endorsed former President Donald Trump and is known as having the warmest relations with Vladimir Putin in the bloc — wrapped up a NATO summit in Washington on Thursday before traveling to Trump's Mar-a-Lago compound — his latest stop on what he calls a "peace mission" aimed at brokering an end to Russia's war in Ukraine.

The German government said Friday that it "won't be intimidated" by Russian attempts to undermine the country's support of Ukraine, but refused to comment on a report that Moscow planned to assassinate the chief executive of a leading defense company.

CNN reported Thursday, citing five unidentified U.S. and Western officials, that American intelligence discovered earlier this year that Russia planned to kill Rheinmetall CEO Armin Papperger. It said the U.S. informed Germany, whose security services were able to protect Papperger and foil the plot. Rheinmetall is a major supplier of military technology and artillery rounds for Ukraine.

Sudan's warring parties have arrived in Geneva at the invitation of the United Nations to discuss the protection of civilians through possible local cease-fires, U.N. officials said. But one side did not show up for the talks on the first day.

Turkish President Recep Tayyip Erdogan said Thursday that any possibility of a direct confrontation between Russia and NATO was "worrying," the official Anadolu news agency reported.
