As the week begins, here's a look ahead and a roundup of key developments from the past week.
What to watch this week
Another week began with Russia launching a wave of attacks hitting Ukraine's capital Kyiv and other areas, causing damage including outages in electricity, cellphone service, water supplies and other destruction.
There will likely be fallout after Russia pulled out of a United Nations-brokered deal to export Ukrainian grain. The U.N. Security Council is meeting to discuss the issue Monday.
What happened last week
Progressive Democrats sent, then withdrew, a letter urging President Biden to seek diplomacy with Russia toward a cease-fire in Ukraine. Thirty members of Congress had signed the letter, which caused a backlash, including from fellow Democrats, but some signatories explained they signed it soon after it was drafted in early summer and much has changed since.
Russia practiced conducting a nuclear strike on Oct. 26, in its first big nuclear drill since invading Ukraine this year. The Kremlin's defense minister said it was a rehearsal for responding to a nuclear attack. It came as NATO carried out its annual Steadfast Noon nuclear exercises.
President Vladimir Putin repeated the allegation, without evidence, that Ukraine is preparing to set off a dirty bomb. The U.S. and allies dismiss this as a false pretext for Russia's own possible future actions.
Germany's president acknowledged a "bitter failure" of his and other governments' policies toward Russia. In his national address on Oct. 28, President Frank-Walter Steinmeier said Russia's war has "reduced the European security order to ashes."
Russia accused Ukraine of a "massive" drone attack on its Black Sea fleet and civil ships over the weekend, off the coast of Crimea. Moscow also alleged "British specialists" were involved in directing the drones as well as damaging gas pipelines, which London denied.
Russia suspended its role in a deal allowing Ukrainian grain to be exported through the Black Sea, citing the alleged drone strikes. The move drew condemnation from Western leaders and the U.N., which brokered the arrangement to ease a global food crisis.
