asian trbune says:
According to sources in the Sri Lanka Army, LTTE who are fighting desperately a losing battle have started attacking troops with CS (2-chlorobenzalmalononitrile) gas. It is said that it is a substance that is used as a riot control agent and is generally accepted as being non-lethal substance if it is not mixed with any other chemicals.
Already Asian Tribune in its 02 January 2006 issue warned of the manufacture of nerve gas by the LTTE. Asian Tribune pointed out that, "Latest intelligence reports are also concerned about the use of thermo baric weapons against the Security Forces. The Tamil Tigers are suspected of having used thermo baric weapons in its latest attack on 23 December, to kill 13 Navy personel at Pesalai."
