Hungarian President-elect Katalin Novak visited the small town of Beregsurany on Tuesday. The town is a mile from the border with Ukraine.

Beregsurany, which has a population of about 600 people, has seen an influx in refugees fleeing Ukraine. Some days as many as 3,000 people pass through it.

The town has responded by setting up a local welcome center to facilitate registration, offering temporary beds until more permanent homes become available and providing counseling and care.

Novak is a member of Hungary’s far right, populist political party and closely works with Prime Minister Viktor Orban, known for his hardline stance on immigration and strict asylum policies.

Novak met with reporters after handing out pancakes to some of the refugees, a tradition started by a group of local women who make hundreds of pancakes daily for everyone coming over the border.

Novak said Hungarians are a welcoming people and want to help those who are fleeing violence and forced to leave their homes.

When pushed on why the politics are different for these refugees, compared to refugees from other countries like Syria, she said Hungary will always welcome people fleeing violence, but the country’s stance on mass migration remains the same.

She did not explain why certain people are considered "mass migration" and others are "seeking asylum."

Save the Children is calling for an immediate ban on intercountry adoptions of children uprooted by Russia's invasion of Ukraine to protect them from human traffickers or child abusers.

The international children's charity warned in a statement Tuesday that "during mass movement of refugees, well-meaning people may attempt to 'rescue' children from the crisis-affected area in the mistaken belief that they will be better cared for in other environments." But Save the Children stressed that "the best place for children is with their families and communities, and adoption is not an appropriate response for unaccompanied children until authorities and agencies have made all efforts to trace and reunite them with their families."

The organization also warned that "not everybody attempting to foster or adopt children from Ukraine does so with the best intentions."

Save the Children is calling on states to support a moratorium on all adoptions "until appropriate safeguards are in place" for the unaccompanied children who have fled Ukraine as well as those who have been uprooted within the country. Ukraine has suspended its intercountry adoption program until further notice in the wake of the ongoing war. But Save the Children noted that "it is important for receiving countries to also suspend intercountry adoption proceedings to ensure the appropriate international standards and safeguards."

Save the Children staff in Romania have reported seeing some kids arriving from Ukraine unaccompanied, while others have been separated from their families in the chaos of fleeing their homes. The organization said many are under 14 and showing signs of psychological distress.

"There is so much upheaval in a child’s life during this time that the best place for them is with their families, relatives, and communities, rather than being removed to a foreign country and language. The most protective environment for a child is the safety and stability of their own family," Amanda Brydon, global head of child protection advocacy for Save the Children, said in a statement. "At this stage of this crisis, an immediate moratorium on intercountry adoptions is critical to ensure that children are safe and that where possible and in their best interests, they are reunited with their caregivers or verified family members. Sending funds to trusted humanitarian agencies for their response to this crisis is one of the best ways to be able to support such children currently."
