A private plane crashed into a vacant office building Sunday outside Milan, Italy, killing all eight people aboard.

The flight had six passengers and two crew members. According to first responders, only those aboard were killed and there were no other injuries.

The plane departed from Milan's Linate city airport and was headed for the Italian island of Sardinia.

The aircraft — a PC-12, a single-engine, executive-type plane — “hit the building and started burning,” according to local reports.

An investigation of the crash is underway.

A Milan prosecutor, Tiziana Siciliano, told reporters at the scene that the plane seemed to be flying normally until “a certain point, then an anomaly appeared on the radar screen and it plunged.”

The plane reportedly did not send out an alarm before crashing.

Only two of the victims have been identified so far because they had their documents with them. Those aboard were all foreigners and the aircraft was registered in Romania. An Italian news report said the pilot, 30, was Romanian and that a second victim was identified as a Romanian woman in her 60s.
