A projected 8.3 million refugees are expected to flee Ukraine, according to the latest assessment by the United Nations High Commissioner for Refugees (UNHCR).
Around 5.2 million refugees had left Ukraine as of Monday, the latest UNHCR data shows.
The UNHCR and partner organizations are seeking $1.85 billion to support Ukrainian refugees in neighboring countries, UNHCR spokesperson Shabia Mantoo said Tuesday.
Speaking in Geneva at the launch of an updated regional refugee response plan to support Ukrainian refugees, Mantoo said the plan "aims to ensure timely and life-saving humanitarian assistance to refugees fleeing Ukraine and third-country nationals, of whom a sizeable number would need international protection."
The plan will also focus on "solutions through the promotion of social and economic opportunities," Mantoo added.
In addition to those fleeing the country, more than 7.7 million people are internally displaced in Ukraine, according to the latest International Organization for Migration report, bringing the total number of those forced to flee their homes to 12.9 million.
There were also almost 13 million people estimated to be stranded in affected areas or unable to leave due to security risks, Mantoo said.
