British Foreign Secretary Boris Johnson has urged allies fighting the Islamic State (IS) to do more to gather evidence of war crimes by the group.
Speaking on Thursday at a conference in Washington on his first US visit, Johnson said the UK would lead a campaign to bring the group to justice, BBC reported.
Addressing foreign and defence officials from about 30 countries involved in the fight against IS, Johnson said more needed to be done to collect evidence in the territory the group has lost.
Witnesses would need to be identified and data collected so that individuals could be held to account and prosecuted, the Foreign Secretary was quoted as saying.
