Hundreds of anti-government protesters have staged a rare - and unauthorised - opposition rally in Almaty, Kazakhstan's largest city.

Demonstrators said the ruling party's victory in this month's parliamentary election was flawed, and they called for the release of jailed opposition activists.

Hours later, speakers at Saturday's rally were handed two-week jail sentences for holding the unsanctioned gathering, according to local media reports.
