A light aircraft crashed into an empty office building in Milan shortly after take-off, according to Italian media reports. The pilot and all five passengers were killed in the accident on Sunday, the reports said. The tourist plane had taken off from Milan Linate airport and crashed only a few kilometres later on its way to Olbia in Sardinia. The building then caught fire. Due to renovation work, no people had been staying there. The reason for the crash was initially unclear.
