Parents in Ukraine put their children's bracelets with their name, a mobile number and their blood type on their hands. "As a mother, it scares me," who lives in Dnipro, eastern Ukraine.

Hanna Syva lives with her family in a block of flats in Dnipro. She told BBC reporters how her life had changed in recent days since Ukraine was attacked.

When the invasion began, she moved her whole family into the living room to sleep behind the couch. On the window sill, next to a large plush toy, is a weapon.

Hanna has two children and she is trying to be optimistic. He admits that he smiles just so he doesn't worry about them.

"They cried yesterday, they are very nervous, so I can't afford to be scared," she said.

He put bracelets on the two boys with their names printed on them, a cell phone number and their blood type.

"It was incredible for me when I put the blood type data for paramedics. As a mother, it scares me," she said.

Meanwhile, all the people in the boat mobilized, she said. She and her neighbors cleared the basement and arranged it so that they could take shelter there. At the front door he has prepared bags with change of clothes, food and water.

In Kiev, a child sleeps for a few days in the bathroom, the safest place in the apartment.

Meanwhile, in Kiev, Olga, a woman living in the western part of the city. Her son, just a few years old, Vadim, is sleeping in the bathroom these days, because that is the safest place in the apartment.

"I sit next to him and caress him when he dreams badly," she told CNN. "We do not go to the shelter, it does not guarantee 100% safety, and this can affect a child's psyche. At home, he sleeps well, eats and thinks that everything is fun," the woman said.

Olga said she heard many explosions between 1:00 and 4:00 on Saturday morning.

Moscow officials say Russian troops are not targeting civilian targets in Ukraine. However, in less than three days since Russian President Vladimir Putin gave the order to invade Ukraine, 198 civilians were killed. Russian weapons hit a kindergarten and several blocks of flats.

Russian Foreign Minister Sergei Lavrov on Friday tried to calm the world over civilian casualties.

"No one will attack the people of Ukraine," he told a news conference, adding that "there were no blows to the civilian infrastructure."

However, reports of bombed buildings and kindergartens, civilians killed and rockets found on residential streets have surfaced since the offensive began.

Videos from social networks, photos and satellite images analyzed and geolocated by CNN confirm that several times densely populated areas have been hit by Russian forces.

Amnesty International has accused Russian forces of "indiscriminate attacks on civilian areas and blows to protected objects, such as hospitals", citing three examples, including a Thursday attack on a hospital building in Vuhledar in the eastern Donetsk region. The attack killed four civilians and injured ten others, according to Amnesty.
