The trial has started in Burkina Faso of 14 men accused of killing former President Thomas Sankara 34 years ago.
Sankara brought in radical socialist reforms and was a prominent campaigner for Pan-Africanist causes.
He was shot dead during a coup in October 1987, which saw his friend, Blaise Compaoré, come to power.
In April a military tribunal accused Mr Compaore of being complicit in the killing. He is exiled in Ivory Coast, denies guilt, and refuses to stand trial in person.
Twelve of Sankara’s comrades were also killed, and a lawyer for the victims’ families says Mr Compaore’s absence suggests he has something to hide.
