The Iranian authorities have accused a shadowy group called Jundullah – the Soldiers of God – of carrying out a suicide bombing on 18 October which killed six commanders of the Iranian Revolutionary Guards. But what is Jundullah, what does it want – and who is behind it?
It was founded in 2002 to defend the Baluchi minority in the poor, remote and lawless region of south-east Iran.
Its leader, Abdolmalek Rigi, denies the group has either foreign links or a separatist agenda.
