Iran links US, Britain to explosion in mosque that killed 14

Iranian officials claim the US and Britain are linked to a group responsible for an explosion in a mosque last month that killed 14 people.

Immediately after the April 12 explosion in the southern city of Shiraz, officials said it was caused by a bomb. But the following day, they changed the account and said it was caused by ammunition leftover from a recent military exhibition in the mosque. (AP)
