The BBC report that UK and US intelligence agents foiled a chemical bomb plot in the UK. Apparently the plot was involves detonating a combination of explosive and osmium tetraoxide, [OsO₄].The target is thought to be in crowded areas, possibly within a confined area, perhaps in London. The plotters apparently did not obtain any of the tetroxide, perhaps because it costs around UK pounds 100 per gram!
