EXIN AN26 landed on belly in Tallinn Airport
 

At the moment it is very unclear what exactly happened.
According to pictures plane is resting on the runway with landing gear completely retracted. While news agencies are telling that it was an aborted takeoff.
Important thing is that nobody wasn't injured nor was there any fire.

Plane on the runway is (SP-FDP) of the same company "EXIN" and type "AN26" that landed on Ülemiste lake ice in March this year.

TLL is certainly not a lucky place for those guys... and vice versa. Quite couple of cancellations happened today for this incident.

It seems to be in landing configuration(Flaps)...

There is a rumor that landing gear lever was pulled before leaving runway. When there is a pressure on landing gear, it won't retract. But when pressure is relieved (plane has taken off), landing gear is automatically retracted. It could be that there was some unfortunate windshear or vibration lifting the aircraft temporarily before actual takeoff initiating automatic landing gear retraction and leaving aircraft on belly with damaged propellers/engines.
There have been similar incidents before.

That could explain why airplane came to a stop way before the end of the runway and why landing gear was completely retracted.

Accident: Exin AN26 at Tallinn on Aug 25th 2010, gear collapse during takeoff

There are some proofs to rumors that landing gear lever was pulled before leaving runway:
-----------
An employee of this company Miroslaw Lawrynowicz said that the cause was human error accident. - .
During the run, after lifting the front wheel, the flight engineer retracted gear- said Lawrynowicz

Rescue chief of TLL Toomas Mardo said that after aborted takeoff the plane skidded approximately 1km along the runway. He saw the incident and described that there was a fire of sparks emitting from belly of the skidding plane. It was kind of miracle that the plane didn't catch the fire and everybody got out of the plane without any injuries.
