Investigate IS war crimes, Johnson urges foreign ministers
UK Foreign Secretary Boris Johnson has urged allies fighting the so-called Islamic State group to do more to gather evidence of war crimes.
Speaking at a conference in Washington on his first US visit in his new role, Mr Johnson said the UK would lead a campaign to bring the group to justice.
He warned of the potential dispersal of IS fighters around the world after they are pushed out of Iraq and Syria.
Mr Johnson proposed a UK summit to examine how to tackle the new threats.
Addressing foreign and defence officials from about 30 nations involved in the fight against IS, Mr Johnson said more needed to be done to collect evidence in territory the group has lost.
Witnesses would need to be identified and data collected so individuals could be held to account and prosecuted, he said.
