Malaysia Prime Minister Anwar Ibrahim said he discussed the downing of Malaysian Airlines Flight MH17 with Russian President Vladimir Putin during a visit to Moscow, days after a U.N. report found Russia responsible for the disaster.

Russia was responsible for the downing of the Malaysia Airlines flight, MH17, over eastern Ukraine in July 2014, the United Nations aviation agency has ruled. All 298 people on board the passenger plane were killed when it was shot down by a Russian-made missile.

Malaysia has a ‘moral responsibility’ to seek justice for the victims, even if it means jeopardising Russia relations, experts say.
