The RSF was created under Bashir in 2013, emerging from the Janjaweed militia that his government unleashed against non-Arab ethnic minorities in Darfur a decade earlier, drawing accusations of war crimes.
The latest violence sparked by the two generals has reflected the deep-seated divisions between the regular army and the RSF.
Despite the wide calls for a ceasefire, the two generals appeared in no mood for talks.
Burhan, who rose through the ranks under the three-decade rule of now-jailed Bashir, has said the coup was "necessary" to include more factions in politics.
Daglo later called the coup a "mistake" that failed to bring about change and reinvigorated remnants of Bashir's regime ousted by the army in 2019 following mass protests.
