[One week into conflict in Ukraine]
[half a million children
are now refugees.]
[The conflict could become one
of Europe's largest refugee crises]
[since the Second World War.]
[UNICEF and partners are reaching
vulnerable children and families]
[with essential health, education,
protection and water services]
[and scaling up its response
to meet the urgent needs.]
[of refugee children and families.]
[The only way out of the tragedy
unfolding in Ukraine]
[is for the conflict to end.]
