From the BBC:

Iran has executed a journalist accused of involvement with a Sunni militant group blamed for a spate of attacks in the south-east, officials have said.

Judiciary spokesman Ali Reza Jamshidi said Yaqoub Mehrnehad and another man were hanged on Monday in Zahedan, the capital of Sistan-Baluchistan province.

Mr Mehrnehad was convicted in February of being a member of Jundallah and of "crimes against national security".

He was arrested in Zahedan last year while reporting for a Tehran newspaper.

Reports say the journalist also ran a charity apparently focused on improving childhood education.

From the Guardian:

The judiciary spokesman said Mirnehad's conviction was not related to his work as a journalist, but gave no further details.
