The head of the United Nations Ebola response mission in West Africa has said that there is a "huge risk" that the lethal virus could spread to other countries as well.
According to the BBC, Tony Banbury declined to comment if targets he had set in the battle against Ebola, to be achieved by Monday, had been met.
The targets were for the safe burial of highly infectious bodies and for the proportion of people being treated.
In Sierra Leone's capital, bulldozers were cleaning large areas for a new burial ground.
The ultimate goal of the UN is zero Ebola deaths which was set to bend the upward curve in the graph of deaths.
The World Health Organization said in its latest report that 6,928 people have died from Ebola and 16,000 have been affected.
