Ukraine's forces in recent days have made "notable progress" against Russian troops in the south of the country, a White House spokesman said on September 1 as Ukrainian officials reported Russian missile strikes overnight.
White House national security spokesman John Kirby told reporters that the United States had seen progress near the Zaporizhzhya region in the last 72 hours.
"They have achieved some success against that second line of Russian defenses," Kirby said. He also acknowledged criticism of Ukraine's counteroffensive "by anonymous officials," saying this was "not helpful."
"Any objective observer of this counteroffensive, you can't deny...that they have made progress now," Kirby added.
The Ukrainian military in recent days has claimed success in penetrating Russian lines between the village of Robotyne and Verbove in the Zaporizhzhya region, and Western battlefield analysis have confirmed the gains.
Ukraine's military said earlier that its counteroffensive was continuing in the country's east and south.
Russian shelling killed a man in the southern Ukrainian city of Kherson, the regional military administration said.
Three people were wounded when a private enterprise was hit by a long-range cruise missile in the early hours of September 1 in the city of Vinnytsya, a city about 200 kilometers southwest of Kyiv, Governor Serhiy Borzov wrote on the Telegram messaging app.
