Thousands of people are believed to have died in the past week as a result of the Russian invasion of Ukraine.
Vladimir Putin launched an attack on the neighbouring country in the early hours of Thursday, February 24, striking major cities with missiles and advancing troops on the capital of Kyiv.
The total number of people who have lost their lives as a result of the crisis is difficult to determine - but some official agencies have released estimates of the death toll so far.
Hundreds of civilians, as well as soldiers, have been killed in the fighting.
Here's what we know about the latest estimated deaths tolls as of Thursday afternoon.
According to the office of the UN High Commissioner for Human Rights, at least 227 civilians have been killed and 525 wounded since the invasion began.
However, on March 2, Ukraine’s State Emergency Service said it believed that a total of more than 2,000 civilians have died in a week of war with Russia.
Estimates of deaths have also been provided for individual attacks in some of Ukraine's main cities.
On March 3, shelling was reported in the northern city of Chernihiv, where emergency officials said at least 22 civilians had been killed in a Russian bombardment of a residential area. They warned that the number of casualties could grow as rescuers search the debris.
On Tuesday, March 1, five people were reportedly killed in an air strike near to a TV tower in Kyiv. One of the five has been named as Ukrainian TV cameraman Yevhenii Sakun.
On Monday, February 28, Ukrainian authorities said that dozens of people had been killed and hundreds more wounded in rocket strikes in Kharkiv, a city of about 1.5 million people.
The Mayor of Kharkiv put the confirmed number of people killed in the attack at nine. He also said 37 people had been injured, including three children.
Another Russian strike that hit the regional police and intelligence headquarters in Kharkiv is understood to have killed four people and left several wounded, according to the emergency services.
