While U.S. diplomats began returning to Lviv for day trips on Tuesday, Secretary of State Antony Blinken said Wednesday that he hopes to move toward reopening the U.S Embassy in Kyiv in the "next few weeks."

Blinken appeared on Capitol Hill Wednesday for his second of three days of testimony about the Biden administration's budget request.

Blinken said the administration will put forward a request for supplemental funding in the "next couple days" after President Joe Biden exhausted the funding in his presidential drawdown authority to provide weapons and other military aid immediately to Ukraine.

That "robust" assistance request will include funding for aid to Ukraine and other U.S. partners and allies and for a functioning U.S. Embassy in Kyiv, he said.

Microsoft has released a detailed report of what it says are "destructive" Russian cyberattacks on Ukraine, which the company says seem "strongly correlated and sometimes directly timed with its kinetic military operations."

"For example, a Russian actor launched cyberattacks against a major broadcasting company on March 1st, the same day the Russian military announced its intention to destroy Ukrainian 'disinformation' targets and directed a missile strike against a TV tower in Kyiv," Microsoft said. "On March 13th, during the third week of the invasion, a separate Russian actor stole data from a nuclear safety organization weeks after Russian military units began capturing nuclear power plants sparking concerns about radiation exposure and catastrophic accidents. “

Microsoft said it has observed nearly 40 attacks "targeting hundreds of systems."

The company said "32% of destructive attacks directly targeted Ukrainian government organizations" while "more than 40% of destructive attacks were aimed at organizations in critical infrastructure sectors that could have negative second-order effects on the Ukrainian government, military, economy and people."

The World Bank issued a report on Tuesday that said the war in Ukraine dealt a major shock to commodity markets and altered global patterns of trade, production and consumption in ways that will keep prices at historically high levels through the end of 2024.

"Overall, this amounts to the largest commodity shock we’ve experienced since the 1970s," Indermit Gill, the World Bank’s vice president for equitable growth, finance and institutions, said in a statement.

The report said energy prices are expected to rise more than 50% in 2022 before easing in 2023 and 2024.

Wheat prices are forecast to increase more than 40%, putting pressure on developing economies that rely on wheat imports, especially from Russia and Ukraine, according to the World Bank.

Metal prices are projected to increase by 16% in 2022 before easing in 2023, according to the report.

Crude oil prices are expected to average $100 a barrel in 2022, its highest level since 2013 and an increase of more than 40% compared to 2021, the report said. Oil prices are expected to moderate to $92 in 2023, which is above the five-year average of $60 a barrel, the World Bank said.

Jalina Porter, the State Department's deputy spokesperson, is responding to the Russian attack at a Ukraine train station that killed at least 50, saying, "We can no longer be surprised by the Kremlin's repugnant disregard for human life."

Five children were among those killed when Russian rockets struck the station in Kramatorsk in Donetsk Oblast on Friday morning, according to Ukraine's state-owned railway company. At least 100 people were injured, according to Donetsk Oblast Gov. Pavlo Kyrylenko.

Russia has denied involvement in the attack, which occurred as "thousands" of civilians fleeing the Russian invasion were at the train station waiting to be taken to "safer regions of Ukraine," according to Kyrylenko.

"Civilians are killed when they stay in their homes, and they're killed when they try to leave," Porter said. "Actions like these demonstrate why Russia did not belong on the U.N. Human Rights Council, and they also reinforce the U.S. assessment that members of Russian forces are committing war crimes in Ukraine."

Porter declined to say if the department considers the train station attack a war crime, saying, "Assessing individual criminal liability in specific cases is the responsibility of courts, as well as other investigatory bodies. But as the secretary, Secretary [of State Antony] Blinken, has said, 'Those responsible for war crimes and other atrocities committed in Ukraine will be held to account.'"
