The U.N. Human Rights Council voted by 21 votes to eight on Friday in favour of prolonging an inquiry into human rights in Yemen, overriding objections from Yemen and Saudi Arabia.

Supporters of the resolution, including Canada and the European Union, had argued that an expert group mandated by the Council last year still had work to do, but opponents said it would exacerbate the crisis and increase regional instability.

In a report last month, the experts said air strikes by the Saudi-led coalition in the war in Yemen had caused heavy civilian casualties and some may amount to war crimes. Saudi Arabia rejected their findings.
