Sudan murals commemorate protest 'martyrs'

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 street art campaign had been launched in response to a brutal raid on a weeks-long sit-in in the capital on June 3 that left dozens of demonstrators dead and hundreds wounded.
