Ukraine has launched long-range drone and missile attacks on key Russian targets. Authorities said Monday that these included an ammunition plant, an oil terminal in Crimea and a weapons depot. The strikes are part of Ukraine's strategy to pressure Russia's military logistics. Ukrainian President Volodymyr Zelenskyy said the country is using domestically produced weapons and aims to expand these capabilities with foreign funding. Ukraine's defense industry is growing with plans to export surplus weapons by the end of the year. The country hopes to provide at least half of its front-line weapons needs with domestically produced arms.

A Russian rocket attack targeted the northeastern Ukrainian city of Sumy, killing at least four people and wounding 25. President Volodymyr Zelenskyy denounced Tuesday's assault, saying it underscored that Moscow has no intentions of halting the 3-year-old war. The attack came a day after direct peace talks in Istanbul made no progress on ending the fighting. Local authorities said the barrage of rockets struck apartment buildings and a medical facility in the center of Sumy. Meanwhile, Ukraine's secret services said they struck inside Russia again, two days after a spectacular Ukrainian drone attack on air bases deep inside the country.
