An angry mob in Bangladesh stormed a fertilizer factory yesterday, clashing with workers after the plant released a toxic gas that sickened more than a dozen local residents, police said. Fifteen people fell badly ill yesterday after inhaling toxic fumes from the newly built fertilizer factory near the Bangladeshi capital, police said "Fifteen people were taken to hospital after becoming seriously ill from inhaling gas emitted by a chemical factory at Fatullah," police officer in-charge Mohammad Shafiqullah said. People living in the residential area near the factory complained to authorities late Friday after their cows fell ill and the leaves of trees turned a reddish color, he said.
