1MDB scandal: What does US say money was spent on?
US authorities have said they plan to seize more than $1bn (£761m) in assets allegedly bought with funds diverted from Malaysia's government investment fund, 1MDB.
The fund was a government project to develop Malaysia's economy, but the Department of Justice (DoJ) has alleged that vast amounts of the fund's money was actually spent by a few individuals on luxury assets around the world. Officials at 1MDB have denied any wrongdoing.
Here are some of the ways the US says the money was spent.
Hotels and luxury homes
The DoJ alleged that $380m was spent on a stake in the Park Lane, a luxury hotel overlooking Central Park in New York.
Another property, Park Laurel Condo, also in New York, cost $33.5m at purchase, the US claims.

A Bombardier Global 5000 private jet was purchased for a reported $35.4m.
