In Sudan, the belligerents currently occupy a national health laboratory. The biological risks are very high according to the World Health Organization, because the laboratory contains samples of measles, cholera and polio pathogens.
Clashes that broke out in mid-April in Sudan have already left 459 dead and 4,072 wounded, the WHO also said Tuesday. Up to 270,000 people could flee from Sudan, Chad and South Sudan, says the UN refugee agency (UNHCR), after a 72-hour ceasefire was reached between the warring parties.
