Latest Russia-Ukraine war news: Live updates

President Biden unveiled an enhanced U.S. posture in Europe on Wednesday, announcing that the NATO alliance would be “ready for threats in all directions.” The new U.S. military deployments include a permanent headquarters for the U.S. 5th Army Corps in Poland — a move that Russian President Vladimir Putin has long resisted — as well as the deployment of two more F-35 fighter jet squadrons to the United Kingdom. Further “air defense and other capabilities” will be sent to Italy and Germany, while additional rotational deployments will be set up in Romania and the Baltic region, Biden said.

Biden will meet with Turkish President Recep Tayyip Erdogan on the second day of the NATO summit on Wednesday. Turkey agreed the day before to drop its opposition to the NATO bids of Sweden and Finland, and a formal invitation is expected Wednesday, putting the alliance on the cusp of growing to 32 members and highlighting how Russia’s war in Ukraine is transforming regional security. In a phone call with Erdogan on Tuesday, Biden encouraged him to “seize this moment” and get a deal done, a senior U.S. official said.

In eastern Ukraine, Russian forces are making incremental gains as they try to encircle the strategic city of Lysychansk, Britain’s Defense Ministry said in its Wednesday update. Lysychansk’s twin city, Severodonetsk, fell to Russia on Saturday.
