MH17 crash: Concern over crash site remains

There have been renewed calls for tighter security at the site of the Malaysia Airlines plane crash in Ukraine, after reports it had been left abandoned.

On Thursday, the BBC witnessed human remains still lying near the road side there.

Meanwhile, the bodies of more victims of the MH17 disaster are being flown to the Netherlands for identification.

About two-thirds of the 298 people who died were Dutch.
