Three years on and there are still many unanswered questions behind the downing of Malaysia Airlines flight MH17.
Relatives of victims are still waiting for someone to be held accountable.
The Boeing 777 was shot down over Ukraine in July 2014, claiming the lives of all 298 people on board.
Most of the victims were from the Netherlands.
Thirty-nine Australians were also killed.
International investigators have concluded that the missile that shot down the plane was fired from Russia-backed rebel-controlled territory by a mobile launcher, brought in by truck from Russia and hastily returned there afterwards.
Moscow rejects the claim.
The Dutch foreign ministry says it will launch criminal proceedings against those responsible for shooting down the plane.
Malaysian Transport Minister Liow Tiong said he is confident he will find the culprits of the plane tragedy.
“The investigation still ongoing, until hopefully end of the year or early next year, we can get a decision on who we can actually charge in court. And we are hoping that the person who actually shot or launched the Buk missile to come forward to tell us what was happening on that particular day.”
Around 90 family members of the 43 Malaysians killed in the crash attended a service on Thursday where they were briefed on the latest developments in the investigation.
Mohamad Salim bin Sarmo’s son died in the MH17 tragedy.
He hopes the Malaysian government is doing its best to ensure justice is served.
“We were told that we will know everything soon and that is just a matter of time before the culprits can be brought to justice. This is what we been waiting for.”
In the Netherlands, King Willem-Alexander and Queen Maxima will join Prime Minister Mark Rutte for the unveiling of a national monument for the victims of the flight.
The monument consists of 298 trees, one for each victim, planted in the shape of a ribbon and a memorial plaque.
