A trial court in Iran has issued its final verdict, ordering a Christian pastor to be put to death for leaving Islam and converting to Christianity, according to sources close to the pastor and his legal team.

Supporters fear Youcef Nadarkhani, a 34-year-old father of two who was arrested over two years ago on charges of apostasy, may now be executed at any time without prior warning, as death sentences in Iran may be carried out immediately or dragged out for years.

It is unclear whether Nadarkhani can appeal the execution order.
