According to a US official, Russian President Vladimir Putin has now committed 90% of its pre-staged combat power into Ukraine, reported Reuters. Russian troops are just outside of Kharkiv now, the official continued, and Mariupol is still under Ukrainian control but Russian forces appeal to be trying to isolate the city.

The official said that the US cannot confirm or deny the use of Russian thermobaric weapons in Ukraine, but knows that 480 Russian missiles have been launched so far. The majority of missile launches have come from inside Ukraine, the official said, who also emphasised that the US does not have boots on the ground in Ukraine. Overhead imagery has been impacted recently by poor weather, the official added.
