The UN's civilian death toll in Ukraine related to Russia's invasion surpassed 3,000 Monday, a grim milestone as casualties from the war continue to pile up.
The Office of the United Nations High Commissioner for Human Rights said in a statement that 3,153 people have been killed in Ukraine since Russia invaded the country.
The true civilian death toll is likely to be higher due to the difficulty in confirmation of reports from heavily besieged regions, and Ukrainian authorities have estimated thousands of more civilians have died as a result of the war.
Most of the deaths were caused by the use of explosives with a wide impact area, as the Ukrainians and their allies accuse the Russians of targeting civilians with shelling and missile strikes.
The majority of the deaths occurred in the Donbas region of eastern Ukraine, which has become the focus of Russia's offensive.
In Mariupol, the mayor estimates at least 10,000 civilians have been killed in the war. According to the latest estimates, about 15,000 Russian troops have been killed in the war, compared to about 2,500 to 3000 Ukrainian troops who have been killed in the invasion.
Russia is accused of committing war crimes in Ukraine by the International Criminal Court. The international justice system is unlikely to bring those responsible for the civilian attacks to justice even if they are found guilty.
More than 5 million. More than 10% of the pre-war population of Ukraine have fled since the war began, according to the U.N. Refugee Agency.
Estimates show that Russian troops have been hit harder in the war.
Over 10,000 Mariupol residents have died.
