HC Deb 03 July 1967 vol 749 cc170-1W
63. Mr. Biggs-Davison

asked the Secretary of State for Foreign Affairs what are the latest reports he has received as to the use of poison gas in the Yemen; and as to the types of gas used.

Mr. George Thomson

We have received well-substantiated reports that lethal gas was used several times during May in the mountainous region east of Sana. There has also been a less well-substantiated report of it having been used again in the Yemen last month. Both a mustard-gas type and a choking gas have been used on different occasions.
