Fresh Russian drone strikes continued to target Ukraine's energy and civilian infrastructure on March 25, causing blackouts in several regions and the capital, Kyiv.
Air-raid signals sounded in the morning hours in Kyiv and several large explosions were reported. Officials reported that falling ballistic-missile debris had damaged a residential building and that at least 10 people were injured across the city.
Air-raid warnings were also heard in nine other regions, including Kherson, Mykolayiv, Odesa, and Dnipropetrovsk.
Russian drones overnight struck the southern city of Mykolayiv. The city's mayor, Oleksandr Sienkevych, wrote on Telegram that 11 civilians were injured and several residential buildings damaged by "falling debris."

Vitaliy Kim, head of the Mykolayiv regional military administration, reported that an Iranian-made Shahed drone started a fire at an "energy facility" in the region.
A Russian drone attack against the Black Sea port city of Odesa caused power outages.
"There is damage to the energy infrastructure," wrote Oleh Kiper, head of the regional military administration, on Telegram. "There is no electricity supply to part of Odesa. All emergency services are working."
Russia has intensified its attacks against Ukraine's electrical grid in recent days. On March 23, officials in Kyiv reported that more than 1 million civilians were without power.
Ukrainian Energy Minister Herman Halushchenko told journalists on March 25 that it would cost "billions" to repair the damage, although he did not specify what currency he had in mind. The World Bank estimated earlier this year that the cost of reconstruction in Ukraine would be at least $486 billion.
Volodymyr Kudrytskiy, board chairman of Ukrenerho, said on March 23 that the country had boosted energy imports from Europe to help compensate for the losses.
"In many regions, however, there is quite significant and large-scale damage to the energy infrastructure," he said. "Their scale is caused by the scale of the attacks themselves."
In the Kharkiv region, some 200,000 people were reportedly without power, according to the head of the regional military administration. In Kharkiv, Ukraine's second-largest city, the metro system was running with delays due to power shortages, Oleh Synyehubov, head of the regional military administration, reported.
Local authorities in the Kharkiv region have instituted a system of hourly power blackout until at least March 31.
In Russia, the Defense Ministry reported that 11 Ukrainian drones had been "intercepted" over the southern Rostov region.
The governor of the region, Vasily Golubev, posted on Telegram that a fire had broken out at a major power and heating plant in the region after locals had reported explosions in the area. Golubov said there were no casualties and that the cause of the fire was under investigation.
