A week after Malaysia Airlines flight MH17 came down in Ukraine, the crash site has yet to be secured raising concerns that vital evidence will be lost.

A BBC team visiting the site on Thursday morning found the scene deserted with no sign of any investigators.

The rebels have promised secure access to the site, but fighting is getting worse and on Wednesday Ukraine said two of its military jets were shot down.

Fergal Keane reports from Donetsk.
