While many foreigners have fled the fighting in South Sudan, an international group of Catholic volunteers has remained at the side of the people they came to serve.

"None of our group has left the country because of the violence.

Being in solidarity means being one with the people.

It means standing faithfully beside them at this tragic time," Sister Cathy Arata, a School Sister of Notre Dame from New Jersey, said in a phone interview from Juba, the nation's capital.
