South Sudan's military spokesman says 24 people were killed and dozens wounded during a battle between government troops and rebels who had overrun a town.

Col. Philip Aguer said Monday that a battle in Jonglei state on Sunday killed 20 rebel fighters and four government troops.

Aguer said the army recaptured the town of Boma, near the border with Ethiopia, from rebels led by David Yau Yau who took over the town earlier this month.

Aguer said government forces found food manufactured in the East African country of Eritrea on the ground, but that officials don't have evidence that Eritrea is helping the rebels.

South Sudan accuses Sudan of supporting Yau Yau's rebellion in order to block South Sudan's plans to build an oil pipeline through Jonglei state and Ethiopia.
