The number of Ukrainians who fled the country since Russia's invasion two months ago is approaching 5.2 million, according to the UN refugee agency.
The total figure of 5,186, 744 is an increase of 23,058 over Saturday's data, the UNHCR said.
There are more than 1,151, 000 Ukrainians left during April, compared to 3.4 million in the month of March alone.
The figures come as Ukrainians celebrate Easter Sunday.
For the people of Ukraine, and those forced to flee the country, it will be another day of fear, anguish, loss and separation from loved ones, as war continues to rage without mercy, the UN High Commissioner for Refugees Filippo Grandi wrote on Twitter.
May strength and courage be with them. Since February 24th, an additional 218,000 citizens of third countries - largely students and migrant workers - have escaped to neighbouring countries, according to the International Organization for Migration IOM.
Women and children account for 90 percent of those who have fled abroad, with men aged 18 to 60 eligible for military call-up unable to leave.
The IOM estimates that more than 7.7 million people have been displaced within Ukraine.
Nearly two-thirds of Ukrainian children have had to flee their homes, including those who are still in the country.
Before the invasion, Ukraine had a population of 37 million in the regions under government control, excluding Russia-annexed Crimea and the pro-Russian separatist-controlled regions in the east.
According to UNHCR: Here is a breakdown of how many Ukrainian refugees have fled to neighbouring countries.
Nearly six out of 10 Ukrainian refugees -- 2,899, 713 -- have so far crossed into Poland.
Many of them have travelled to other states in the Schengen open-borders zone.
There are more than 800,000 people who have crossed Poland into Ukraine, Polish border guards said.
Before the war, Poland was home to around 1.5 million Ukrainians, chiefly migrant workers.
As of April 22, a total of 774,074 Ukrainians have entered the EU member state, including a large number who crossed over from Moldova, wedged between Romania and Ukraine.
The vast majority of people are thought to have gone on to other countries.
Another 578,255 refugees have sought refuge in Russia, according to data last updated on April 21.
Between February 18 and 23, 105,000 people crossed into Russia from the separatist-held pro-Russian regions of Lugansk and Donetsk in eastern Ukraine.
The Moldovan border is the closest to the major port city of Odessa. A total of 433,214 Ukrainians have crossed into the non-EU state, one of the poorest in Europe. Most of them have moved on.
A total of 354,329 people have crossed the Ukraine's shortest border into Slovakia.
As of April 21st, another 24,084 refugees made it north to Russia's close ally, Belarus.
