Two Russian agents jailed for murdering a former Chechen leader in Qatar have lost their appeal.
Yanderbiyev had spent the last three years in exile in Qatar
A Qatari court upheld life sentences imposed on the two men found guilty of killing Zelimkhan Yanderbiyev in a bomb attack in February.
The trial judge said the men had been acting on orders from the Russian leadership. Russian officials deny the two men were involved in the killing.
Mr Yanderbiyev, a former Chechen rebel president, lived in exile in Doha.
The appeal court in the capital, Doha, upheld the original verdict and sentence.
"The court rejects the appeal in contents and the earlier
verdict is upheld. This decision is final," said presiding judge
Abdallah al-Saadi said.
Mr Yanderbiyev was killed by a device which had been placed under his car and exploded as he left a Doha mosque after prayers. His son was injured in the attack.
Russia insists the two agents jailed for the killing were in Qatar to gather anti-terrorism intelligence.
The affair has caused tension in the relationship between Qatar and Russia.
Yanderbiyev was vice-president of Chechnya for most of the first war with Russian forces from 1994 to 1996.
He took over the presidency when the leader of the Chechen independence movement, Dzhokhar Dudayev, was killed by a Russian missile in April 1996.
It is believed that Mr Yanderbiyev and his family went to Qatar in January 2000.
Russia tried to have Mr Yanderbiyev extradited, but the Qatari authorities said they believed he would not face a fair trial.
