Police in Slovenia say a small plane has crashed in the west of the country, killing all four people on board.

Police official Dejan Boznik says the U.S.-registered Piper 32 came down on Thursday near the town of Ajdovscina, about 80 kilometers (50 miles) west of the capital Ljubljana. Boznik says the victims are foreign citizens.

Slovenia's Traffic Control says the pilot reported problems with icing before disappearing from the radar around 10:30 a.m.

Slovenian media say the plane was flying from Venice, Italy, to Leipzig, Germany. The official STA news agency says the plane was completely destroyed and the victims' bodies were charred when found by rescuers.
