"Members of Security Council highlighted the urgency of the medical response because the disease can spread rapidly, including to neighboring countries, possibly impacting regional stability," the Council said in a statement.DRC's 10th Ebola outbreak since the first known case in 1976 came on August 1 in a highly restive northeastern region home to a clutch of armed groups near the border with Uganda, Rwanda and South Sudan.The latest outbreak has killed at least 101 people, according to the World Health Organisation.
