Moscow has acknowledged its forces have fallen back north of Ukraine's battlefield city of Bakhmut after a new offensive, in a retreat the head of Russia's Wagner private army called a rout.

Russian forces have likely withdrawn from their positions on the southern flank of Bakhmut operations in bad order in the past four days, Britain's defence ministry said in its daily intelligence update on Saturday.

* The Ukrainian military said in a daily update Russia was focusing its efforts near Lyman, Bakhmut, Avdiivka and Marinka. "The enemy carried out 36 attacks in these directions in the last 24 hours."

DIPLOMACY AND ECONOMY

* South African officials hit back on Friday at US accusations a sanctioned Russian ship had picked up weapons from a naval base near Cape Town late last year, a move investors feared could lead Washington to impose sanctions.

INSIDE RUSSIA

* Pro-war Russian nationalists led by Igor Girkin said on Friday a new group they had set up was entering politics to save Russia, which they warned was in danger of turmoil due to military failures in the Ukraine war.
