Sudanese protester Walid Abdelrahim was shot dead last month in Khartoum but for his mother he is still alive -- thanks to a colourful mural of his smiling face on a wall of their home.

The portrait is part of a campaign launched by Sudanese artist Assil Diab to draw murals and graffiti to commemorate demonstrators killed in the months-old protest movement that has rocked the northeast African country.
These murals are specifically drawn on the walls of protesters' own homes or in their neighbourhoods.

Diab, a former employee of Doha-based Al-Jazeera television network, and her team got their motivation from a protest catchcry: "Our martyrs didn't die, they are alive among the revolutionaries!"
"Graffiti makes martyrs come alive and reminds people of them even if the people themselves did or did not support the revolution."
