While there are some signs that the Sudanese army is getting the upper hand against the paramilitary Rapid Support Forces (RSF) in Khartoum, the conflict in Darfur is intensifying. General Mohamed Hamdan Dagalo, the RSF leader, has placed trusted men in charge of its units in the vast region.
US intelligence agencies are closely following the activities of Sudan's deputy junta leader in Chad, the Central African Republic and in his own country.
