Over 300 children have been killed or injured in Sudan's war over the past six months, mostly as a result of drone strikes, the U.N. children's agency said Monday.

Sudan has been mired in a war between the Sudanese military and the paramilitary Rapid Support Forces since April 2023.

The war is now concentrated in the Kordofan, Darfur and Blue Niles states, with drone warfare causing 60% of casualties, according to UNICEF.

The U.N., U.S, U.K. and others have expressed alarm about potential atrocities as the RSF and the military fight for control of the strategic city of el-Obeid, in North Kordofan.

In Geneva Monday, the U.N.-backed Human Rights Council approved a measure, which was brought by five European countries, condemning the escalating violence by the RSF and its allies in and around el-Obeid.
