We're now closing our live page on the conclusions of the Dutch Safety Board into why flight MH17 crashed.

Here's what we've learned:

• Malaysian Airlines Flight MH17 crashed as a result of a Russian-made Buk missile, the Dutch Safety Board says
• The missile hit the front left of the plane causing other parts to break off, killing 298 people
• The West and Ukraine say Russian-backed rebels brought down the Boeing 777 but the report does not say who fired the missile
• Airspace over eastern Ukraine should have been closed, investigators say
• The report says the three crew members in the cockpit were instantly killed by the missile explosion

Separately, Russian officials from Almaz-Antey - the state firm that manufactures Buk missiles - said the evidence suggested the plane had been shot down by a surface-to-air Buk missile fired by Ukrainian forces.

We've compiled five key findings from the report that you can read here.

Rebuilding the front of the Boeing 777 was a painstaking task - and involved the recovery of thousands of fragments over a large area in a war zone.

"Only in rare cases (are) aeroplanes reconstructed after a crash," the report says. "Such a process is labour-intensive and time-consuming."

Despite the report not apportioning blame, Russian Deputy Foreign Minister Sergey Ryabkov has dismissed it as an "attempt to draw a biased conclusion, to carry out a political order".

He said more attention should have been paid to the findings of Russian arms manufacturer Almaz-Antey.

The company said experiments it carried out contradict the conclusion that it was a Buk missile of the kind used by the Russians that brought the plane down.

It says the missile could have been a model of Buk that is no longer used by the Russian military but is part of the Ukrainian military arsenal.

If you have 20 minutes free, here's the video put together by Dutch investigators detailing what they say occurred to flight MH17.

If you don't have 20 minutes to spare, here's our summary.

And here is the original report, external, in English, that was published today.

Dutch PM Mark Rutte says a criminal investigation "will be complex and will take a great deal of time" - the report, he says, will form a large part of the evidence.

The Joint Investigative Team based in the Netherlands said in a statement that, external "it needs to be examined who had any role in the shooting down of flight MH17 and what was their intention".

But, the statement says, finding witnesses and getting them to make a statement in a safe environment is "not easy".

There's been plenty of reaction from Malaysia over the past few hours.

In a statement, Transport Minister Liow Tiong Lai said: "Malaysia remains single-minded in our pursuit of decisive action that will lead to prosecution of the trigger-happy criminals."

Prime Minister Najib Razak said his government would pursue justice "until those behind this heinous act are made to pay for their crimes".

As well as the Dutch and Russian investigations, a number of other groups and individuals have conducted their own inquiries into the disaster.

Chief among them is the Bellingcat investigative group, external - but here are the words of one Dutch man who tried to get to the bottom of what happened.

The father of British victim Liam Sweeney described a private briefing for families, held prior to the publication of the report, as "quite composed".

Most of those who died were from the Netherlands, but there were others from Malaysia, the UK, the Philippines and a number of other countries.

Here is what we know about the 298 people who lost their lives.

So what exactly did Dutch investigators conclude about what happened to flight MH17?

Here's our guide to the main conclusions - the animation was produced by the Dutch Safety Board.

But what more don't we know about what happened? Handily, we have produced this guide for you.

Back in October last year, the then-Foreign Minister of the Netherlands, Frans Timmermans, said one body was found at the crash site with an oxygen mask attached. It's a comment he later said he regretted, for the upset it caused victims' families.

This point is addressed in one part of the report (see page 99, external) - but it remains unclear as to who the victim was.

The mother of one of the MH17 victims has told the BBC that the plane should have been nowhere near eastern Ukraine.
