A third round of talks between Russia and Ukraine ended without any resolution.
Russian forces are continuing their attempted push through Ukraine from multiple directions, while Ukrainians, led by President Volodymyr Zelenskyy, are putting up "stiff resistance," according to U.S. officials.
The attack began Feb. 24, when Russian President Vladimir Putin announced a "special military operation."
Russian forces moving from neighboring Belarus toward Ukraine's capital, Kyiv, have advanced closer to the city center in recent days despite the resistance, coming within about 9 miles as of Friday.
Russia has been met by sanctions from the United States, Canada and countries throughout Europe, targeting the Russian economy as well as Putin himself.

In a new letter to House Democrats, Speaker Nancy Pelosi reiterated plans to approve new aid for Ukraine in a government funding measure this week.
She also said new legislation to ban the import of Russian oil and energy products would repeal normal trade relations with Russia and Belarus and deny Russia access to the World Trade Organization.
The measure would also give the administration more power to raise tariffs on Russian imports.
Pelosi said Congress and the Biden administration “remain laser-focused on bringing down the higher energy costs for American families and our partners,” noting that 60 million barrels of oil have been released from strategic reserves and allies have said they will reduce their dependence on Russian energy.
“With the West’s carefully coordinated effort to sequence sanctions on Russia and mitigate for the costs of these efforts, we are standing up for our values abroad while protecting our families at home,” Pelosi wrote in the letter.
It’s not clear when the House will take up this measure, but Congress needs to approve government funding -- which will include the Ukraine aid -- by Friday.

A planned Russian strike targeting military-industrial facilities will result in countless civilian casualties, Ukrainian President Volodymyr Zelenskyy warned in a new address.
He began his latest speech by saying that on a day recognized by Ukrainians as “Forgiveness Sunday,” there will be no forgiveness for Russia.
“We will not forgive shooting our people and destroying our infrastructure. Hundreds upon hundreds of victims, immeasurable suffering. God will not forgive this, not today, nor tomorrow, never,” Zelenskyy said.
The Russian Ministry of Defense announced on Sunday it will use high-precision weapons to destroy Ukrainian military-industrial facilities.
Zelenskyy warned those sites are in urban areas surrounded by civilian residences. “Hundreds of thousands of people live and work there,” he said. “This will be a premeditated murder, but today I haven’t heard any reaction from any world leader or any politician.”
He said Russia was openly announcing a “planned atrocity” in advance because there is no reaction from the international community.
“Well, I hope you’ll at least say something tomorrow when you’ll see it happened,” Zelenskyy said. “We know exactly how these attacks will be carried out, we know the full chain of command, we know everything, and we’ll forgive nothing.”

Approximately 600 Russian missile launches have taken place since the invasion of Ukraine began on Feb. 24, a senior defense official said.
They could not corroborate any reports of the use of cluster munitions or thermobaric weapons.
Ukrainian air and missile defenses are still effective and in use, the official said, though the airspace over Ukraine is contested.
Both sides have taken losses to aircraft and missile defense inventories, the defense official added, and while they did not reveal exact numbers, they believe both Russia and Ukraine still have a majority of their air defense systems.
The official also said Russian forces are still trying to advance across the north and east of Ukraine but are being met with strong Ukrainian resistance. The convoy is still stalled.
