Former President Donald Trump spoke heatedly in the presidential debate about wanting Russia's war in Ukraine to be over — but twice refused to directly answer a question about whether he wanted U.S. ally Ukraine to win.

Trump also falsely claimed Tuesday that the war had killed "millions" since Russia invaded Ukraine 2 1/2 years ago, while the United Nations says 11,700 civilian deaths have been verified. Trump also claimed without evidence that Vice President Kamala Harris, his Democratic opponent, had bungled a diplomatic mission just days before Russia launched the invasion.

Kamala Harris put Donald Trump on the defensive in a fiery televised debate Tuesday, getting under her rival's skin as they battled for a breakthrough in an agonizingly close U.S. presidential election.

U.S. Secretary of State Antony Blinken and British Foreign Secretary David Lammy arrived together in Kyiv on Wednesday on a joint trip to assess Ukraine's requests for more military help.

The top diplomats of the two allies arrived by train from Poland in the Ukrainian capital, according to an AFP reporter travelling with them, ahead of a day of meetings with senior officials in Kyiv.

Germany, France and Britain on Tuesday condemned what they said was Iran's delivery of ballistic missiles to Russia for use in the Ukraine war and declared new sanctions targeting air transport.

"We will be taking immediate steps to cancel bilateral air services agreements with Iran," they said in a joint statement, adding that they would also "work towards imposing sanctions on Iran Air."

Ukraine is gearing up for a harsh winter by repairing and protecting its power system under renewed attacks from Russian forces, Prime Minister Denys Shmygal said on Tuesday.

Pope Francis celebrated a mass for hundreds of thousands of faithful in East Timor on Tuesday, rallying nearly half the population of the world's most Catholic country outside the Vatican in stifling tropical heat.

Ukraine has increased its production of weapons this year, Prime Minister Denys Shmygal said Tuesday as outgunned Ukrainian troops are trying to fend off invading Russian troops.

"In the first eight months of 2024, we have doubled our weapons production compared to 2023. We are making progress. Drone production continues to grow," Shmygal said, adding that Ukraine planned to build over one million drones by the end of the year.

Over 140 Ukrainian drones overnight targeted multiple Russian regions, including the capital Moscow and the surrounding areas, Russian officials reported Tuesday, in one of the biggest Ukrainian drone attacks on Russian soil in the 2 1/2-year war.

In the town of Ramenskoye just outside Moscow, drones hit two multistory residential buildings and started fires, Moscow region Gov. Andrei Vorobyov said. A woman was killed and three more people sustained injuries. Five residential buildings near one of those damaged have been evacuated as emergency services were handling drone debris, Vorobyov said.

Two NATO members said that Russian drones have violated their airspace, as one reportedly flew into Romania during nighttime attacks on neighboring Ukraine while another crashed in eastern Latvia the previous day.

A drone entered Romanian territory early Sunday as Moscow struck "civilian targets and port infrastructure" across the Danube in Ukraine, Romania's Ministry of National Defense reported. It added that Bucharest had deployed F-16 warplanes to monitor its airspace and issued text alerts to residents of two eastern regions.

China's Defense Ministry on Monday announced joint naval and air drills with Russia starting this month, underscoring the closeness between their militaries as Russia presses its grinding invasion of Ukraine.

The ministry said the "Northern United-2024" exercises would take place in the Sea of Japan and the Sea of Okhotsk farther north, but gave no details.
