Nearly $700 million of deposits were made into what are believed to be the personal bank accounts of Malaysia's Prime Minister Najib Razak, according to documents from a government investigation of a controversial state investment fund, the Wall Street Journal reported Friday.

The document shows the movement of cash from 1Malaysia Development, or 1MDB, through government agencies, banks and companies, before it landed at Najib's accounts, directly connecting the prime minister to the deeply indebted fund for the first time, the WSJ reported.
