The United Nations says fighting between government troops and pro-Russian separatists in eastern Ukraine has left more than 300 people dead in less than a month, taking the overall toll to 4,634.
Some 10,243 people have been wounded since the conflict began in April, the UN's OCHA humanitarian agency OCHA said in a statement on December 13.
The statement said that more than 1.1 million people have been displaced - 542,080 internally and 567,956 fleeing to neighboring countries, the vast majority, 465,721, to Russia.
According to the report, some 5.2 million people live in conflict-afflicted areas.
The OCHA's last report on the Ukraine crisis on November 20 had put the death toll at 4,317.
