Agence France Presse reported: In a statement, US Army announced on Sunday that US troops found a large bomb-making factory just north of Baghdad. The factory was being used to assemble explosively-formed penetrators, the fist-sized bombs that can cut through heavy armour.

AFP added: US commanders say that members of the covert operations arm of Iran’s Revolutionary Guards have been supplying the explosives and training Shiite militiamen in their use, a charge Tehran strongly denies.

The US military said the bomb-making factory was found in the town of Husseiniyah and contained 10 fully assembled EFPs of various sizes.

Troops also found around 90 copper plates and more than 90 kilogrammes (200 pounds) of C-4 explosive, enough material to make at least 150 EFPs, the statement said.
