It said more than 300 people have been admitted to Juba Teaching Hospital and Juba Military Hospital over the past two days.
The ICRC and the South Sudan Red Cross have delivered to the hospitals enough wound-dressing materials and other urgently needed medical supplies to treat up to 500 people, said the statement.
“We know there are more people who need care, but they are having difficulty reaching health-care facilities because of the security situation and the lack of available transportation,” said Felicity Gapes, an ICRC delegate who is leading a medical response on the ground.
The ICRC is calling on the fighting parties to take all feasible precautions to minimize civilian casualties and to allow people to safely reach health-care facilities, added the statement, adding the organization is closely monitoring needs.
It also said together with the South Sudan Red Cross, it will take further action as the security situation permits.
