GENEVA (AFP) - Fighting between government troops and pro-Russian rebels in Ukraine has left more than 300 people dead in less than a month, taking the overall toll to 4,634, the UN said on Saturday in its latest report on the conflict.

Some 10,243 people have been wounded since the conflict erupted in the ex-Soviet republic's east in April, UN's humanitarian agency OCHA said in a statement.

More than 1.1 million people have been displaced - 542,080 internally and 567,956 fleeing to neighbouring countries, the vast majority, 465,721, to Russia, it said.

Some 5.2 million people live in conflict-afflicted areas, it said.

OCHA's last report on the Ukraine crisis on November 20 had put the toll at 4,317.

A tentative ceasefire has been in place along the frontline in eastern Ukraine since Tuesday, and fighting has been greatly reduced despite occasional breaches.
