The UN peacekeeping mission in the country has been exploring the site of Sunday's attack against aid workers. Six aid workers were killed in that attack. They were South Sudanese and Kenyan nationals. A convoy of peacekeepers accompanied members of the ceasefire monitoring mechanism to inspect the site. The attack took place more than 50 kilometres from the capital, Juba. Several other people, including a driver and an army officer were also killed in the attack.
