Tehran - Iran Friday hanged three people convicted of being involved in a bomb explosion in a mosque in the southern city of Shiraz in 2008, Iranian media reported. Mohsen Eslamian, Ali-Asghar Pashtar and Rouzbeh Yahyazadeh - all members of Tondar, a previously unknown terror group - had been arrested last year and convicted by a revolutionary court, state-run IRIB television reported.

Fourteen people were killed and about 200 injured in a bomb explosion during a speech by a local cleric in a Shiraz mosque in April last year.

An appeals court upheld the verdict by Tehran's revolutionary court which found all three guilty and convicted them to death, the station reported on its website.

Under Iran's sharia law armed robbery, murder, adultery, drug smuggling and involvement in "terrorist acts" are punishable by death.
