NEW: An explosion that ripped through a wedding celebration in southern Iran on Tuesday, killing four people (including 2 minors) and injuring at least 68 others, likely resulted from a direct hit by a U.S. munition and not a ricochet off another target, according to an analysis by weapons experts who reviewed images and video verified by Reuters. I spoke with 4 munitions analysts who agreed that the strike on the wedding gathering was a direct hit. Three experts said it was unlikely that a misfired Iranian missile had destroyed the home. Thank you to @Easybakeovensz, @bastischutte & Gareth Collett for your insights. I also spoke with @haalvsh and @balochistanhrdn to confirm local accounts of what happened the evening of September 1. Many thanks to my hamvatans who spoke with us, despite the continued systematic state intimidation on people speaking with media. Great team effort with Edward Carron, @idreesali114, Emily Giles, all of @ReutersWitness & @SarahCahlan reuters.com/investigations/d…
