MH17: Netherlands mourns

The country will observe a national day of mourning to remember victims of flight MH17.

Bodies of victims wrapped in bags wait to be collected at the site of the crash of a Malaysia Airlines plane carrying 298 people from Amsterdam to Kuala Lumpur in Grabove, in rebel-held east Ukraine, on 19 July, 2014.

AMSTERDAM - A national day of mourning is being observed in the Netherlands today to remember victims of Malaysia Airlines flight MH17.

A train carrying the remains of many of the 298 victims of MH17 arrived in a Ukrainian government-held city on Tuesday on the first leg of their final journey home to be reclaimed by their families.

Five refrigerated wagons containing 200 body bags reached the city of Kharkiv after pro-Russian separatists agreed to hand over the plane's black boxes to Malaysian authorities and the bodies to the Netherlands, where many victims had lived.

The train slowly rolled into the grounds of an arms industry plant, where the remains are due to be unloaded and flown to the Netherlands for the lengthy process of identification.

The first plane carrying the bodies is expected to land around 4pm in Amsterdam.

The Boeing 777 was flying from Amsterdam to Kuala Lumpur when it was shot down near Donetsk, a stronghold of pro-Russian rebels, where fighting with Ukrainian troops flared again on Tuesday.

There's a general sense of relieve that most bodies and black boxes, crucial to the investigation, have been recovered.

There are still many more unanswered questions however, as investigators prepare to launch their investigation on the crash site.

A representative of the OSCE European security watchdog said there were still human remains left where the Boeing 777 hit the ground in eastern Ukraine last Thursday.

"We did not observe any recovery activity in place," spokesman Michael Bociurkiw said after his group inspected the site earlier in the day.

Western governments have threatened Russia with broader sanctions for what they say is its backing of the militia.

However, they are struggling to agree a response, and European Union ministers meeting in Brussels on Tuesday delayed action for a few days.

Russian President Vladimir Putin said he would urge the separatists to allow a full investigation which the Netherlands said it would lead. Malaysia said it would send the black boxes to a British lab for analysis.

"Here they are, the black boxes," separatist leader Aleksander Borodai told journalists at the headquarters of his self-proclaimed Donetsk People's Republic as an armed rebel placed the boxes on a desk.

Malaysian Prime Minister Najib Razak, speaking to parliament in Kuala Lumpur on Wednesday, maintained his stand that blame should not be apportioned pending an investigation.

"A few hours after MH17 crashed, officials in the US and Ukraine claimed it was shot down," Najib said.

A small group of Malaysian air crash experts became the first international accident investigators to reach the site on Tuesday, escorted by a convoy of international monitors and heavily armed separatist fighters.

As they went about their work, loud explosions were heard on the outskirts of Donetsk, some 60 km from the site One shell was sticking out from a hole outside a residential block with a pool of blood next to it.

The shooting down of the airliner has sharply deepened the Ukrainian crisis, in which separatist gunmen in the Russian-speaking east have been fighting government forces since pro-Western protesters in Kiev forced out a pro-Moscow president and Russia annexed Crimea in March.
