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.

Russia claims troops took control of more settlements, damaged Ukraine's military infrastructure
Russia's Defense Ministry on Saturday claimed its troops continued to disable military infrastructure in Ukraine and took control of Ukrainian settlements.
Russia claimed its troops took control of seven Ukrainian settlements and that Russian-backed troops in Donetsk moved 7 kilometers forward, Russian Defense Ministry spokesperson Igor Konashenkov said at a briefing.
"Units of the Russian Armed forces are advancing as a wide front and have taken control over populated areas of Mala Tokmachka, Marfopil, Remivka, Novokarlivka, Orlinske, Volodine and Malynivka," Konashenkov said.
Konashenkov claimed that Luhansk's Russian-backed troops took hold of the settlements of Golikove, Nevske and Katerynivka.
Russia claimed it destroyed five radar stations and two Buk M-1 air defense systems and that it downed four Su-27 aircrafts over Zhytomyr and one Su-27 aircraft near Nizhyn, according to Konashenkov.
Konashenkov also said that Russian troops are resuming their offensive "due to the Ukrainian side's unwillingness to influence the nationalists or prolong the ceasefire," Konashenkov said.

US State Department tells Americans to depart Russia 'immediately'
The U.S. State Department on Saturday updated its travel advisory for Russia amid the war in Ukraine and Russia's tightening crackdown on dissent, reporting and travel and the worsening economic situation, including declined credit cards and cash shortages.
"U.S. citizens should depart immediately," the advisory warns, adding, "If you wish to depart Russia, you should make arrangements on your own as soon as possible."
The State Department warned Americans, "If you plan to stay in Russia, understand the U.S. Embassy has severe limitations on its ability to assist U.S. citizens, and conditions, including transportation options, may change suddenly."
The State Department further warned U.S. citizens may be harassed by "Russian government security officials" or face "arbitrary enforcement of local law," something they've warned about for years.
The U.S. embassy has issued detailed instructions on how to flee the country, including over land borders by car and bus as well as limited flights.

Russia says it is restarting offensive operations in cease-fire areas
Russia’s Defense Ministry on Saturday announced it will now begin offensive actions again in Ukraine, having never observed the cease-fire it announced earlier in the morning.
A Defense Ministry spokesman, in a briefing, accused Ukraine’s government of failing to restrain “nationalists” or observe the cease-fire saying, “at 18:00 Moscow-time offensive actions are renewed.”
In reality, Russia has continued to shell Mariupol and Volnovakha in Ukraine’s east throughout the day, despite having declared a temporary cease-fire and humanitarian corridor to allow civilians to leave.
Ukrainian officials have accused Russia of using the cease-fire period to move forces closer to Ukrainian positions.
The International Committee of the Red Cross has said evacuations could not take place today because of shelling. The ICRC branch in Donetsk told ABC News earlier, that its team in Mariupol was forced to take shelter because of shelling.

Zelenskyy speaks to more than 300 US lawmakers
Ukrainian President Volodymr Zelenskyy spoke to over 300 senators, members of Congress and top Hill staff on Saturday, pleading for more lethal and military aid.
Zelenskyy, on an hourlong Zoom call, asked U.S. lawmakers for weapons including drones, planes and stingers; the implementation of a "no-fly" zone over Ukraine; a full ban on the import of Russian oil to the U.S.; and a suspension of the use of Visa and MasterCard in Russia.
In a statement made after the call, Senate Majority Leader Chuck Schumer said, “President Zelenskyy made a desperate plea for Eastern European countries to provide Russian-made planes to Ukraine. These planes are very much needed. And I will do all I can to help the administration to facilitate their transfer.”
According to a source who attended the meeting, Schumer started the call by addressing Zelenskyy, saying, “Mr. President, we are inspired by you and the strength and courage of the Ukrainian people. The people of New York and its large Ukrainian community stand with you."
Sen. Lindsey Graham, R-S.C., speaks about a Senate resolution calling for accountability for Russian President Vladimir Putin, March 2, 2022, at the Capitol.

“Senator McConnell and I, along with the other members on this zoom, are working very hard in a bipartisan fashion to get all the assistance the administration has requested for the Ukrainian people. Together we will get that assistance of over $10 billion in economic, humanitarian and security assistance to the Ukrainian people quickly," Schumer said.
One senator on the call told ABC News' Rachel Scott that at one point, dozens of attendees unmuted and said "Thank you, Mr President," "We support you," "Slava Ukraini" and "We will help you."
The senator told Scott that Zelenskyy "was clearly moved by the cascade of voices lifted in support."
Senators Rob Portman and Jeanne Shaheen, who recently traveled to Ukraine, are expected to send a letter asking the Department of Defense to send F16 planes to Eastern European countries who donate MiG aircrafts to Ukraine. Poland has said it is willing to do this.
Another senator told ABC News that there are serious concerns about Zelenskyy's safety, saying, "If he’s dead it makes it that much easier for Russians to seize control. If there isn’t a legitimate government we recognize it’s harder to help."
According to a source, Zelensky said he and his family have been targeted.
The U.S. Department of the Treasury said Friday that sanctions don't start until June and omit Russian oil and gas. Senators are going to call for immediate tightening.
