Russia may believe it needs reinforcements, US says

Russian ground troops have made limited progress over the last 24 hours in their effort to seize major cities in Ukraine, a senior US defense official says.

And as deadly airstrikes continue, the US has seen indications that Russia may believe it needs more troops and supplies than it has on hand in the country, and is considering ways to get resources brought in, says the official, who spoke on condition of anonymity to discuss US military assessments.

The official did not elaborate on the indications, and says that as of today, however, there has been no actual movement of reinforcement troops currently in Russia going into Ukraine.

According to the official, Russian ground forces are still about 15-20 kilometers (9-12 miles) northwest of Kyiv and 20-30 kilometers (12-19 miles) east of the city, which is being increasingly hit by long-range strikes. The official said Ukrainian troops continue to put up stiff resistance in Kharkiv and other areas.

Russia has launched more than 950 missiles so far in the war, and both Russia and Ukraine still retain about 90% of their combat power, the official says.
