Saudi Arabia's foreign minister says $681 million banked into the Malaysian Prime Minister Najib Razak's bank accounts was a "genuine donation."Najib's office said Friday that the confirmation by Adel Al-Jubeir vindicates Najib against allegations that the money was siphoned from heavily indebted state investment fund 1MDB.Al-Jubeir says Saudi authorities were aware of the donation, and that it was given without any strings attached. Malaysia's foreign ministry provided a video clip of Al-Jubeir's comments, made Thursday to Malaysian reporters in Istanbul after a meeting with Najib.Najib has been battling allegations that the money was funneled from 1MDB into his accounts. He was cleared in January by the attorney general, who said it was a donation from Saudi's royal family and that Najib had returned most of it.
