Initial reports indicated no-one was killed in the attacks on two villages on Monday and Wednesday.
On Monday the LRA attacked the village of Kamandare, 40 kilometres (25 miles) from Dembia, close to the border with the Democratic Republic of Congo, the Central Africa military source said.
"They took at least 10 people hostage and ransacked a number of houses," the source said.
"On February 17, the rebels launched another attack, against the village of Gbangomboro, seven kilometres from Dembia, but the villagers had fled following a warning," the source said.
