KAMPALA, Uganda (AP) -- South Sudan government troops are setting villages on fire and abusing civilians in an ongoing military assault on rebels loyal to the country's former vice president, Amnesty International reported Thursday, the latest allegations of serious rights abuses since the resumption of heavy fighting last month.
Citing witness accounts in Unity state, the watchdog group reported Thursday that fighters in South Sudan military uniforms -- and others in civilian clothing --have attacked villages using axes, machetes and guns.
Despite the spike in fighting the international community is "reluctant to take bold steps toward addressing repeated atrocities," Michelle Kagari, deputy director with Amnesty International, said in a statement.
Aid groups have recently pulled out of battle zones, leaving thousands of people in need as rebel forces fight for control of the country's crucial oil fields. South Sudan depends heavily on its oil exports to keep the government running and the military's latest assault is widely seen as an attempt to secure all the oil fields and get them running. But the rebels are fighting back, leaving thousands of civilians caught in the crossfire.
Rebel forces on Wednesday said they were poised to take the oil hub of Paloch in Upper Nile state, but the military said it repulsed the attack.
In its report Thursday, Amnesty International cited the account of women, including a mother of three who recalled being raped by one fighter while another pointed a gun at her.
It was not immediately possible to get a comment from South Sudan's military, which routinely denies such charges.
The alleged rights violations are taking place in areas where there are few independent monitors, with the regional mediating group known as IGAD saying last week its officials were prevented from monitoring the fighting near Bentiu, Unity state's capital.
Journalist Pow James Raeth was shot dead Wednesday by unknown perpetrators in Akobo, Jonglei state, said his employer, South Sudan's Radio Tamazuj. He is the sixth journalist killed in South Sudan this year.
