The United Nations said Saturday that the number of refugees fleeing Ukraine since the Russian-Ukraine conflicts a fortnight ago is nearly 2.6 million.

The UN High Commissioner for Refugees said there were 2,597,543 refugees who had fled Ukraine so far, in the latest update on Saturday afternoon.

The figure was 92,650 higher than the last count on Friday.

Four million people could leave Ukraine, initial UN estimates said, a figure which will likely be revised upwards, according to the UN refugee agency.

Before the conflict, Ukraine had a population of some 37 million.

Poland is hosting over half the Ukrainian refugees with 1,575,703 crossing into the country since the February 24, according to the UNHCR.
