The US has handed down new sanctions on Russia targeting President Vladimir Putin's two daughters in response to what Joe Biden condemned as "atrocities" in Ukraine.
So what do we know about Putin's daughters and why is the US targeting them?
Putin has two daughters with his ex-wife Lyudmila, with the pair marrying in 1983 when she was a flight attendant and he was a KGB officer.
Putin and Lyudmila were married for 30 years until they split in 2013, which Putin said "was a joint decision: we hardly see each other, each of us has our own life" while Lyudmila said he was "completely drowned in work".
Putin has tried to shield his daughters away from the limelight giving very little away about their identities.
"They live in Russia. They have never been educated anywhere except Russia. I am proud of them; they continue to study and are working," he said when responding to questions at a press conference in 2015, saying his daughters had not fled the country, as had been speculated.
"My daughters speak three European languages fluently. I never discuss my family with anyone.
"They have never been 'star' children, they have never got pleasure from the spotlight being directed on them. They just live their own lives."
Putin's daughters are 36-year-old Maria Vorontsova, who is the oldest, and 35-year-old Katerina Tikhonova.
Maria Vorontsova
Vorontsova studied biology at St Petersburg University and medicine at Moscow State University and is now an academic, specialising in the endocrine system.
She co-wrote a book on stunted growth in children and is listed as a researcher at the Endocrinology Research Centre in Moscow.
Vorontsova leads government-funded programs that have received billions of dollars from the Kremlin for genetics research and are personally overseen by Putin, according to details in the US sanctions package announced on Thursday.
People who have spoken to her since the Ukraine invasion say she supports her father and has cast doubt over international reporting of the conflict, BBC reports.
Katerina Tikhonova
Tikhonova is a successful rock n' roll dancer with a fifth-place finish at an international event in 2013.
She is a tech executive whose work supports the Russian government and its defence industry, the US said.
In 2013, she married Kirill Shamalov, the son of Nikolai Shamalov who is a close friend of Putin and co-owner of Rossiya Bank, which the US government has described as "the personal bank" of top Kremlin officials.
Kirill was sanctioned by the US in 2018 for his role in Russia's energy sector, with the US saying "his fortunes drastically improved following the marriage".
Why is the US targeting Putin's daughters?
The US is targeting Putin's daughters because they believe he's hiding his assets with his family.
"We have reason to believe that Putin, and many of his cronies, and the oligarchs, hide their wealth, hide their assets, with family members that place their assets and their wealth in the US financial system, and also many other parts of the world," a senior US administration official told reporters.
Kremlin spokesman Dmitry Peskov said in February the sanctions introduced against Putin were pointless.
"(Putin) is quite indifferent. The sanctions contain absurd claims about some assets," Peskov said. "The president has no assets other than those he has declared."
But the US doesn't agree.
"Putin and his oligarchs stow their dirty money in rule-of-law nations by purchasing mansions, mega-yachts, artwork, and other high-value assets," US Senator Sheldon Whitehouse said a few weeks ago, while introducing legislation that offered cash rewards for information that leads to the seizure of assets held by sanctioned Russian oligarchs.
