HL Deb 28 April 1999 vol 600 c45WA
Lord McNair

asked Her Majesty's Government:

Whether the murder of aid or relief workers by combatants in a civil war constitutes a war crime. [HL2078]

Lord Williams of Mostyn

There is no statutory definition of what constitutes a war crime. However offences committed in the course of armed conflict, both international and otherwise, may be prosecuted under the Geneva Convention Act of 1957. And where the relief or aid worker is deemed to be a member of the United Nations, as defined by the Act, action may also be taken under the United Nations Personnel Act 1997.
