Senior defense official: "We now assess that [Russian President Vladimir" Putin has put in 90% is pre-staged combat power across the border into Ukraine." There's been "heavy bombardment" in cities including Kyiv and Chernihiv.

"We've seen reporting that Kherson is under Russian control, but we're not in a position to independently verify that. In the southeast, our assessment is that Mariupol is still under Ukrainian control." -Senior U.S. defense official

"Airspace over Ukraine remains contested as we said yesterday. We assess that Ukrainian air and missile defense systems remain intact and they remain effective. They continue to be able to fly their airplanes and to employ air defense assets."

"I've seen reports attributed to various US officials about Stinger missiles. I can only say we continue to provide Ukraine systems they need to defend themselves & that includes systems & weapons they can use to deal with the threats on the ground as well as airborne threats."

"As of this morning, we've now counted more than 480 Russian missile launches again of all sizes and stripes" since the start of the invasion last week."

"The majority are coming from inside Ukraine, the next biggest chunk are coming from Russia" and about 70 came from Belarus.

"We still assess that the convoy is that everybody's been focused on is stalled and we have no reason to doubt Ukrainian claims that they have that they have contributed to it being stalled by attacking it." The convoy is 40-miles long and reportedly headed to Kyiv.

"We cannot confirm reports of the use of cluster munitions. We cannot confirm reports of the presence or use of thermobaric weapons."

"Nothing to speak to in the maritime environment ... We don't have any naval activity to speak to or any moves by the Russians with respect to Odessa at this time. Obviously, we're watching it as closely as you can, but we just haven't seen any appreciable activity."

On Russia using 90% of its prepositioned combat power: "Just because they're drawing more on it every day, you should not take away from that that their combat power is being diminished to such a point inside Ukraine that they are feel like they're running out of juice here."

"We still assess that [Russia has] available to them in and outside Ukraine. They still have an awful lot of capability left to them. Just because they throwing in now 90%, we shouldn't take away from that that this is some sort of overreaction or that they are diminished."

"We cannot independently confirm reports that [Kherson] has fallen. Our best information -- and I want to stress the caveat that there's a lot that we don't always know -- is that is that they're still fighting there. But we're not ready to call it one way or another."

"It's probably been 2-3 days since the last time we thought [Russia] made any major geographic distance towards Kiev ... Generally speaking, we still assess that the advanced columns they started moving on Kyiv are roughly about 25 kilometers north of the city."

Pentagon view on Ukrainian President Zelenskyy staying in Kyiv: "Obviously, we remain concerned about his [safety.] It's incredibly noteworthy that he has stayed there in Kyiv [as he] continues to have command & control over his forces. And we commend his bravery for [staying.]"
