Eni fuel depot explosion death toll climbs to four

(ANSA) - ROME, DEC 10 - The death toll of Monday's explosion at an Eni fuel depot at Calenzano, near Florence, has climbed to four after the bodies of two more victims were found early on Tuesday, sources said.
    Another person remains unaccounted for after the blast, in which nine people were injured.
    Three of the nine are in very serious 'code red' condition, suffering from severe burns and blunt-force trauma, the local health authority said.
    The blast was probably caused by a spill, according to an initial reconstruction.
    Some liquid was probably spilled while tanker trucks were being refilled, said investigators. (ANSA).
