Practice Relating to Rule 134. Women
Section C. Death penalty on pregnant women and nursing mothers
The UK LOAC Manual (2004) states:
Pregnant women and mothers of dependent children who are arrested, detained or interned for reasons related to the armed conflict must have their cases considered with the utmost priority. For these women, the pronouncement of the death penalty should be avoided, as far as that is possible, and the execution of the death penalty is forbidden. In any event, United Kingdom courts may not impose death sentences.
