He said FP-5 Flamingo cruise missiles struck the drone and missile plant in the city of Cheboksary, in the Chuvash Republic, more than 900km (560 miles) from the front line. Local officials said three people were injured in a missile attack on the city.

Russia fired more than 620 drones and long-range missiles overnight, killing at least six people in the latest wave of strikes, Ukraine said Saturday, adding that it was close to an agreement to receive more Patriot air-defense systems. "The Russians continue to use their specific tactics of terror against our country, striking concentrated blows at one city or another, at one region or another," Ukrainian President Volodymyr Zelenskyy said in his evening address. Moscow has stepped up aerial strikes over recent months as U.S.-led ceasefire talks have stalled.

A large-scale Russian drone attack in the southeastern Ukrainian city of Dnipro has killed three people, including a young girl, according to the regional governor, hours before officials from the United States, Europe and Ukraine gather in Paris to discuss the conflict. Dnipropetrovsk Governor Serhiy Lysak said the attacks that also injured tens of people came late on Wednesday, triggering multiple fires and damaging a dozen apartment buildings. A student residence, an educational institution and a food processing plant were also damaged, Dnipro Mayor Borys Filatov added. Photos posted online showed raging fires, burned-out vehicles and buildings with shattered windows and scorched facades, as emergency crews worked through the night. Sixteen of the injured are in hospital, one of them in critical condition, according to Lysak.

Ukraine continues to reel from Russia's missile strike on Monday, which ranks as the largest attack since the start of the war, as Moscow is beginning to suggest that Ukraine could make desperate moves. "Russia's large-scale strikes on Ukraine's critical infrastructure on Monday are almost certainly in response to Ukraine's incursion into Kursk Oblast, breaching Russia's border," Rebekah Koffler, told Fox News Digital. "Zelenskyy likely anticipated Russia's retaliation and accepted the risk anyway," Koffler explained. "Zelenskyy wants to stay in the fight - there's no other path for him personally or professionally." "To stay in the fight, he needs more weapons and financing from the West," she added.

Belarusian President Alexander Lukashenko says Kyiv has stationed more than 120,000 soldiers along its border with Belarus, the country's state news agency reported, as fighting continues amid Ukraine's incursion into Russia's Kursk region. Lukashenko, a staunch ally of Russian President Vladimir Putin, said on Sunday that Minsk had deployed nearly a third of its armed forces along the entire border in response to the Ukrainian deployment, BelTA reported. Kyiv did not immediately respond to the claims. "Seeing their aggressive policy, we have introduced there and placed in certain points – in case of war, they would be defence – our military along the entire border," BelTA quoted Lukashenko as saying in an interview with Russian state television. The president made it clear that should Ukraine try to enter Belarusian soil, they will be on the offensive, Jabari added.
