War Crimes are crimes that come under the collective name of 'core international crimes'. Core international crimes are some of the gravest crimes in international law, examples of them can include: the crime of genocide, crimes against humanity, war crimes and torture.
Through international treaties the UK has a responsibility to investigate and prosecute those who have committed core international crimes.
Alternatively, there may be those in the UK who have witnessed offences or are survivors of such crimes.
If a UK resident has been responsible for core international crimes anywhere in the world, they may be investigated and prosecuted in the UK.
Examples of core international crimes can fall under the four different groups listed below.
Violations of the laws or customs of war, including:
atrocities or offences against persons or property, constituting violations of the laws or customs of war
murder, ill treatment or deportation to slave labour or for any other purpose of the civilian population in occupied territory
murder or ill treatment of prisoners of war or persons on the seas
killing of hostages
torture or inhuman treatment, including biological experiments
destruction of property that is of particular cultural significance
It is an offence for a public official or person acting in an official capacity to intentionally inflict severe pain or suffering on another in the performance or purported performance of their official duties, without lawful authority.
Genocide is a crime under international law even if it is not a crime in the country where it takes place, and incitement to commit genocide is also a crime.
Genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group:
killing members of the group
causing serious bodily or mental harm to members of the group
deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part
imposing measures intended to prevent births within the group
forcibly transferring children of the group to another group
Atrocities and offences committed against any civilian population, as part of a widespread attack, including:
mass systematic rape and sexual enslavement in a time of war
other inhumane acts
persecutions on political, racial or religious grounds in execution of or in connection with any other crime against humanity

The following organisations attend meetings of the UK War Crimes Network with police and government agencies. They work to deliver justice for survivors of core international crimes.
The IIIM was set up to assist in the investigation and prosecution of those responsible for the most serious crimes under international law committed in Syria since March 2011. It aims to collect, preserve and analyse evidence of such crimes, and to prepare files in order to assist future prosecutions in national, regional or international courts.
Between June 2014 and December 2017, ISIL captured and controlled large swathes of territory in Iraq, committing grave abuses of international law. UNITAD is an investigative team that aims to support domestic efforts to hold ISIL accountable by collecting, preserving and storing evidence of acts that might amount to war crimes, crimes against humanity and genocide committed in Iraq.
Europol aims to facilitate the cooperation and coordination of EU Member States and Third Parties’ efforts to identify and investigate individuals, networks and groups involved in committing core international crimes through its Analysis Project (AP CIC).
Eurojust hosts the annual EU Genocide Network, to enable close cooperation between national authorities when investigating and prosecuting core international crimes. The Network’s mandate is to ensure perpetrators do not attain impunity within the Member States.
