Sudan's war has entered its fourth year, with millions of people displaced and the country facing one of the world's worst humanitarian crises. Now, allegations that Sudan's military has used chemical weapons are coming under renewed scrutiny.

Sudan's military rejects the allegations as baseless, while the Organisation for the Prohibition of Chemical Weapons says it is seeking clarification. Earlier this year, a France 24 investigation also reported strong evidence of chlorine gas being used as a weapon in Sudan.
