A small explosion injured two women and one man in Battambang province yesterday. The explosion occurred at about 2:30pm, after shop owner Keng Sovanna, 38, of Slaket village in Slaket commune, had filled gas bottles at the shop, Battambang town Police Chief Pen Seng Eun said. “It might be a technical problem with the gas filling,” Seng Eun said. The fire did not spread to neighbouring properties and police are questioning all three injured in the blast.
