FBOWeb.com has a KML of the flight, based on GPS telemetry from their tracking system.

They say a bird strike caused the problem. Crazy a small bird take down an entire plan but it happens. Luckily everybody survived.

A single small bird usually doesn't take down an airliner. The engines must pass a "bird-strike-evaluation"; a frozen chicken (possibly something equal) is "shot" into a running engine. If the engine breaks down, it won't get the neccessary approval.
This morning (in Germany) they talked about a "flock of geese" which is a "little more" than a single small bird ;)

'birdstrike' is just a term. It can describe any number of birds. If it's the cause, it'll come out that the aircraft hit a flock of birds in order to knock out both engines.

They run tests with dead chickens on engines to make sure the turbine blades meet requirements and can ingest a decent sized bird without serious damage. Given the location, it could've been a flock of good sized sea birds or geese that they hit. Perhaps a large number of much smaller birds would have the same effect too.

Here are some videos of bird tests. Not hugely gory, but a little gross for some folks I suppose:
