Virgin Galactic says that its SpaceShipTwo space tourism craft has suffered an "in-flight anomaly".

The craft was being tested in the Mojave Desert region of California. Virgin Galactic said it would issue a fuller statement shortly.

Local police said they were responding to reports of a crash in Cantil.

SpaceShipTwo is carried by a special jet and released, before igniting its rocket to go into sub-orbit and return as a glider.
