Chad's ex-president seeks to overturn his conviction
Chad's ex-President Hissene Habre has gone to court to challenge his conviction for crimes against humanity.

His lawyers argue that the trial by a special court jointly set up by Senegal and the African Union was marred by procedural errors.
They also say the defendant's rights were not respected.
Mr Habre was the first former leader to be convicted by an African Union-backed court - his case was seen as a landmark for the continent.
The former president ruled Chad from 1982 until he was overthrown in 1990 and fled into exile in Dakar, the capital of Senegal.
He was sentenced to life in prison after being convicted of rape, sexual slavery and ordering mass killings.
As his appeal trial opened on Monday, one of his lawyers, Mbaye Sene, told the AFP news agency:
"We were motivated to appeal by the violations of the law and [the rights] of the defence and procedural errors."
Habre says the special court has no jurisdiction over him, and is unlikely to appear in person for the appeal proceedings.
If the court upholds his sentence, he will serve his time in Senegal or in another member country of the African Union.
