The death toll from a bombing at a mosque in southeastern Iran is lower than initially thought. It is now estimated at least 19 people died in last night’s blast at the prominent mosque in the town of Zahedan on the turbulent border with Afghanistan and Pakistan. At least another 80 people were wounded in the explosion.Local authorities have accused the US of orchestrating the assault. Three people have been arrested. Tehran often accuses the US or Israel, which it considers to be its arch-enemies, to be behind such attacks, especially in border regions. The bombing comes ahead of an election in June in which President Mahmoud Ahmadinejad is seeking a second four-year mandate.
