Content_paragraphs:  Security incidents spiked in the north-west, starting from 25 May, primarily
  
  clashes between national defence forces, assisted by bilaterally deployed and other
  
  security personnel, and CPC elements, particularly 3R, which triggered displacement
  
  of the population towards Chad and Cameroon. On 28 May, in Bang, close to the
  
  Cameroonian and Chadian borders in Ouham-Pendé Prefecture, national defence
  
  forces reportedly arrested and tortured approximately 20 civilians from the Muslim
  
  community, including five women, based on their perceived association with
  
  3R combatants. On 30 May, 3R elements reportedly crossed the border into Chad,
  
  following clashes near Bang. National defence forces and bilaterally deployed and
  
  other security personnel reportedly followed in pursuit, resulting in clashes with
  
  Chadian forces and casualties on both sides. On the same day in Bang, bilaterally
  
  deployed and other security personnel obstructed the access of a United Nations
  
  delegation led by the Deputy Special Representative and Resident and Humanitarian
  
  Coordinator. Sporadic gunfire in the border area continued on subsequent days.
