Libya's prime minister says his country expects to extradite to the UK the brother of the Manchester bomber before the end of this year.

Twenty-two people died in the suicide bombing at a concert at the Manchester Arena 18 months ago.

The perpetrator, Salman Abedi, a Briton of Libyan parentage, died - but his brother Hashem was taken into custody in Libya.

He's suspected of involvement, and is wanted by Manchester police on charges of murder, attempted murder, and conspiracy to cause explosions.

Prime Minister Fayez al-Sarraj told the BBC his country was completing the legal moves for his extradition and understood the anguish of the victim's families.
