Four Iranian Christians are awaiting the verdict of an appeal against their one-year jail sentences for spreading Christianity in Iran.

Amin Khaki, Hossein Barounzadeh, Mohammad Bahrami and Rahman Bahmani were sentenced in October 2015. Their appeal was heard on 1 Feb. and the judge is expected to give a ruling soon, reports Middle East Concern.

The four Christians, who are from the self-styled “Church of Iran” network, were first arrested in March 2014 along with four others, during a picnic in the western city of Shush, near the border with Iraq.

After an interrogation, five of them, including Bahrami, were released, but Bahrami was later re-arrested.
