Tributes are being paid to a doctor killed in Khartoum, where he had stayed to look after elderly patients.
Bushra Ibnauf Sulieman, a Sudanese-American medic, was attacked and stabbed in front of his house in the Sudanese capital, later dying in hospital.
He had gone out on Tuesday morning - when the tentative ceasefire began - to take his father to a hospital appointment.
His friend and colleague Yasir Elamin remembers him as “someone who felt firmly that life was about giving back”.
Dr Sulieman had once practised in the US, where he was a founding member of the Sudanese-American Physicians Association, and more recently had been training doctors at home.
“He was someone who believed in Sudan. He spent a significant amount of his time educating the next generation of Sudanese doctors. He was very charismatic ... everybody loved him," Dr Elamin told the BBC World Service's Newsday programme.
It's not thought that Dr Sulieman was killed by either of the warring sides - but rather as a result of the lawlessness now sweeping the city.
Dr Elaim, the current Sudanese-American Physicians Association president, said this kind of disorder was coming as shock to Khartoum residents, as the city has always been regarded as “one of the safest African capitals”, despite conflict elsewhere in Sudan over the decades.
