The government of Southern Sudan has ordered its military, to attack anyone bearing arms outside Ugandan rebel assembly points.
The order by South Sudan Vice president Riek Machar was in response to a call from MPs from south Sudan for the government to deploy more forces in the affected areas.
On June 4, Suspected LRA Rebels overran a military camp on the Sudan-Congo border killing at least 27 people.
According to a ceasefire monitoring team, a Ugandan military squad raided a town on the Sudan-Uganda border, killing one person on June 14.
Machar told the parliament in southern Sudan that the Sudan People's Liberation Army (SPLA) is under instruction that anybody holding arms must be attacked.
The Ugandan military has forces at the border with Sudan, but it remains unclear if and how deeply they have penetrated the country.
In April, Sudan-mediated talks between Uganda and the LRA were ground to a halt, when the elusive rebel leader Joseph Kony refused to sign a peace accord, on the grounds of outstanding International Criminal Court war crimes arrest warrants.
