South Sudanese authorities are investigating an attack which left 40 people, including women and children, dead following a cattle raid by armed youths in South Sudan’s Boma state, South Sudan’s Radio Tamazuj reports.

The dead included 22 women and 17 men, as well as a newborn baby. Nineteen others were also wounded in the attack in Jonglei State’s Duk Payuel County on Tuesday.

The attackers were reported to be members of South Sudanese opposition leader Riek Machar’s Murle tribe which has been at odds with South Sudan President Salva Kiir’s Dinka tribe during the civil war which erupted in the world’s newest country in 2013.

During the attack homes were burnt down, cattle taken and women and children abducted.

In a separate attack on Monday, at least three people were killed and another person wounded during an attack on the area of Pajut in Duk Panyang County, bringing the total number of people killed in greater Duk County to at least 43.

The fighting between the pastoralist Dinkas from Jonglei and their Murle neighbours in Boma state has long involved cattle raids and child abductions.

The fighting continues despite a cessation of hostilities agreement signed in the capital Juba in May.
