Dr M moots rally against Najib in view of damning claims
Former prime minister Dr Mahathir Mohamad has suggested that Malaysians hold a peaceful rally to demand the resignation of Prime Minister Najib Abdul Razak.
"Malaysians are timid. In other countries, millions take to the streets. Malaysians are very nice, we don't normally hold such (protests)."
Bekas Perdana Menteri, Tun Dr Mahathir Mohamad menyarankan kepada rakyat agar mengadakan perhimpunan aman mendesak, Perdana Menteri, Datuk Seri Najib Najib meletak jawatan.
The Department of Justice alleges $3.5bn (£2.6bn) was misappropriated from 1MDB.
"The Malaysian people were defrauded on an enormous scale," Deputy FBI Director Andrew McCabe said at a news conference.
Mr Najib is not named in the suit. But it refers to "Malaysian Official 1", described as "a high-ranking official in the Malaysian government who also held a position of authority with 1MDB".
The move reflects an intention by the US to open new fronts in its fight against illicit finance.
It also sets up a rare confrontations between the US and Malaysia, which is considered an important partner in the fight against terrorism.
What do people involved say?
1MDB responded to the US papers by saying it had not benefited from the various transactions described in the suit.
The fund has repeatedly asserted that it has never given money to the prime minister and called the claims "unsubstantiated".
Mr Najib has also consistently denied taking money from 1MDB or any public funds.
His office said Malaysia had "led the way in investigations into 1MDB" and would "fully co-operate with any lawful investigation".
Is anyone else involved?
Mr Najib has accused his fiercest critic, former Prime Minister Mahathir Mohamad, of using the scandal as a means of "political sabotage".
He claims Mr Mahathir worked "hand in glove" with foreigners as part of a campaign "to topple a democratically elected prime minister."
The BBC put Mr Najib's allegations to Mr Mahathir, who dismissed the claims. Instead, he called on the prime minister to show proof that he didn't pocket state funds.
Opposition leaders have now repeated their call for Mr Najib to stand down.
Over the last year, Mr Najib has also sacked his deputy Muhyiddin Yassin and replaced the former attorney-general over critical comments they made about the scandal.

There have been multiple domestic official investigations into the 1MDB fund, including a special task force headed by the attorney general. The team raided the office of 1MDB in 2015 and took away some documents.
But the replacement attorney general cleared Mr Najib of wrongdoing in January.
Multiple foreign authorities have also been investigating the company.
In May, Singapore ordered Swiss bank BSI to shut down in the city-state for breaking its money-laundering laws in its dealings with 1MDB.
Swiss authorities have opened criminal proceedings related to 1MDB on "suspected corruption of public foreign officials, dishonest management of public interests and money laundering".
What do Malaysians think about it?
The 1MDB controversy has frustrated many Malaysians who are struggling with the rising cost of living and what is perceived to be ingrained corruption in its political system.
Last year tens of thousands of protesters took to the streets calling for the resignation of the PM.
However, thousands of ethnic Malays have also rallied in support of the government.
The reaction on Thursday to the US move has been muted in both Malaysia's mainstream newspapers and social media.
Malaysia's government has cracked down on reporting of the 1MDB scandal, blocking access to certain online news portals and targeting media groups and journalists.
