Indo-China War

There are a number of examples of locahzed conflicts where CWs have been intentionally used but cannot be verified e.g. in 1951-1952 in the Korean War in 1963 the Egyptians used mustard bombs against Yemeni royalists in the Arabian peninsula in the Indo-China War (see Vietnam War) in 1970, in Angola antiplant agents were almost certainly used and in former Yugoslavia, there were rumors of the use of psychotomimetic agents.
