Sudan's army says it has detained children who were "forced" to fight alongside the paramilitary Rapid Support Forces (RSF) in the ongoing conflict.
State-owned Sudan TV says the unspecified number of children are held in Wadi Saidna, northern Khartoum.
On 15 September, SAF handed over 30 children who were held as prisoners of war to the International Committee of the Red Cross (ICRC).
The RSF has been repeatedly accused of violating international laws by recruiting minors in the ongoing conflict in Sudan.
Meanwhile, the RSF said on Saturday that 260 Sudan army soldiers joined its ranks in Khartoum.
Fighting continues between the army and the RSF in Khartoum, Darfur and Kordofan regions amid reports that renewed talks in Saudi Arabia are focusing on reaching a ceasefire and humanitarian support.
