At least one person was killed and two children wounded when the Sudanese air force on Wednesday dropped bombs on a small village in Rashad locality of South Kordofan.
An eye witness explained that 41 heads of cattle were killed in the incident.
In a separate incident Sudanese Antonov bombed Blue Nile State killing two civilians and wounded four others.
SPLM-N Spokesman Arnu Ngatulu Lodi claimed that SAF dropped 28 bombs in four villages in Kurmuk County on Sunday killing a number of livestock.
He lamented that the Antonov plane bombed the villages throughout the day.
Mr Ngatulu explained that the attack occurred on the same day SPLM-N declared the unilateral cessation of hostilities with the Government.
Khartoum Government continues to bomb civilians in Nuba Mountains and Blue Nile states despite of unilateral ceasefire.
CRN could not verify the claims
