Clashes flared in parts of Sudan on the 100th day of the war on Sunday as mediation attempts by regional and international powers failed to find a path out of an increasingly intractable conflict.

The fighting broke out on April 15 as the army and paramilitary Rapid Support Forces (RSF) vied for power. Since then, more than 3 million people have been uprooted, including more than 700,000 who have fled to neighboring countries.

Some 1,136 people have been killed, according to the health ministry, though officials believe the number is higher.
