Iraqi troops raided a suspected terror cell of five people who specialize in making chemical compounds for sarin, mustard and nerve gases, the defense ministry said Saturday.

The suspected terror cell was broken by military intelligence forces after three months of surveillance, the ministry said.

One of the five people made a "confession" stating the cell was planning to use the chemicals agents in Iraq and other countries, the ministry said.

Iraqi security forces raided two factories -- in Baghdad and in an unspecified province -- and confiscated materials used to manufacture chemical weapons, officials said.
