Russian forces launched a new drone assault across Ukraine overnight on Wednesday, killing three people and wounding 64 others, Ukrainian officials said.

One of the hardest-hit areas was the city of Kharkiv in northeastern Ukraine, where 17 attack drones struck two residential districts, Mayor Ihor Terekhov said. Emergency crews, municipal workers and volunteers worked through the night to extinguish fires, rescue residents from burning homes, and restore gas, electricity and water services.

President Donald Trump called protesters in Los Angeles "animals" and "a foreign enemy" in a speech at Fort Bragg on Tuesday as he defended deploying the military on demonstrators opposed to his immigration enforcement raids and as he vowed to "liberate" the West Coast city.

Trump, in his most aggressive language yet regarding the protests, used a speech ostensibly supposed to be used to recognize the 250th anniversary of the U.S. Army to denounce the protesters while repeating his false statements about the 2020 election being rigged and attacking the previous commander in chief, former President Joe Biden.

The Sudanese military said Wednesday it has withdrawn from a key area bordering Egypt and Libya, while the paramilitary Rapid Support Forces (RSF) announced its takeover in a separate statement.

The announcements came a day after the army accused forces loyal to eastern Libyan commander Khalifa Haftar of launching a cross-border attack alongside Sudanese paramilitaries, the first accusation of direct Libyan involvement in Sudan's war.

Iran threatened Wednesday to target U.S. bases across the Middle East if conflict breaks out, as the long-time foes prepare for new round of nuclear talks amid a standoff over uranium enrichment.

"All its bases are within our reach, we have access to them, and without hesitation we will target all of them in the host countries," Defense Minister Aziz Nasirzadeh said in response to U.S. threats of military action if the talks fail.

South Korea on Wednesday halted loudspeaker propaganda broadcasts into the nuclear-armed North, the defense ministry said, adding it was a bid to "restore trust" under Seoul's new administration.

The decision to suspend the broadcasts "was made to make good on a promise to restore trust in South-North Korea relations and seek peace on the Korean peninsula", the defense ministry said in a brief statement, adding the halt started Wednesday.

Los Angeles police began arresting people in the city's downtown late Tuesday, as groups gathered in violation of an overnight curfew after a fifth day of protests against Donald Trump's immigration crackdown.

Marines and additional National Guard troops headed to the Los Angeles area on Tuesday, sent in by President Donald Trump in response to protests over immigration raids despite the objections of the governor and local leaders.

The authorization came amid mostly peaceful protests in the country's second-largest city on Monday. Additional protests against immigration raids are expected to continue in other cities Tuesday.

At least four people were killed in Colombia on Tuesday as rebel groups detonated bombs near police stations in the city of Cali and the neighboring Cauca province, according to authorities.

Military and police spokespeople blamed the attacks on the FARC-EMC, a group led by former members of the Revolutionary Armed Forces of Colombia who broke away from the group after it signed a peace deal with the government in 2016.

A French middle school employee was stabbed to death by a 14-year-old student during a bag check Tuesday at their school in eastern France, authorities said. The student was detained.

A police officer helping with the bag checks was slightly injured during the arrest by the student, using the same knife he used against the school employee, the gendarme service said. The attack at the Francoise Dolto School in Nogent, north of the Burgundy city of Dijon, was being investigated.

Donald Trump made no secret of his willingness to exert a maximalist approach to enforcing immigration laws and keeping order as he campaigned to return to the White House. The fulfillment of that pledge is now on full display in Los Angeles.

The president has put hundreds of National Guard troops on the streets to quell protests over his administration's immigration raids, a deployment that state and city officials say has only inflamed tensions. Trump called up the California National Guard over the objections of Democratic Gov. Gavin Newsom — the first time in 60 years a president has done so — and is deploying active-duty troops to support the guard.
