KAMPALA, Uganda (AP) — The International Committee of the Red Cross says it has withdrawn its staff from a humanitarian compound in a violent county in South Sudan after its office was looted and its aid workers threatened.

The aid group said in a statement Monday that dozens of armed men entered the compound over the weekend and stole equipment, medical supplies and money.

The statement said two vehicles were also taken in the incident that happened amidst intense fighting between armed groups in Leer County in the disputed Unity state.

It also said the group is concerned for the vulnerable people who are left with no access to humanitarian aid.

South Sudan's warring factions signed a peace deal in August, but they accuse each other of launching attacks in violation of the cease-fire.
