Violence in war-torn South Sudan is worsening, neighboring Kenya’s top security body warned Tuesday

Violence in war-torn South Sudan is worsening, neighboring Kenya's top security body warned Tuesday, condemning a "total disregard" by battling forces for a ceasefire deal it helped broker last month.
  
Thousands have been killed and almost 900,000 forced from their homes by over two months of battles between rebel and government forces, backed by troops from neighboring Uganda.
  
Kenya's top defense body, the National Security Council (NSC) -- which is headed by President Uhuru Kenyatta -- called on all sides in the conflict to resume stalled peace efforts, warning of the "cost of inertia" if they did not return to talks.
  
"The NSC expressed deep concern over the continued and escalating military activities in South Sudan in total disregard and violation of the cessation of hostilities agreement," the body said in a statement.
  
The NSC also warned of a "worsening humanitarian crisis including the increased inflow of refugees".
  
Tens of thousands are still crammed into UN bases in fear of ethnic attacks by either President Salva Kiir's Dinka tribe or his former vice-president Riek Machar's Nuer tribe.
