Medical humanitarian NGO, Doctors Without Borders, known by its French initials MSF, says one of its hospitals in South Sudan was hit by a government air strike, amid renewed fighting between soldiers and a coalition of opposition forces in opposition-held areas.

The hospital was “evacuated and patients were discharged hours before the attack” after it received information about a possible strike against the city, MSF said in a statement.

“The hospital’s main warehouse was destroyed during the attack, and we lost most of our critical supplies for providing medical care,” said the statement.

It came after the South Sudanese government in December imposed restrictions on humanitarian access in opposition-held areas of Jonglei, restricting MSF’s ability to deliver essential medical assistance there.
