Israeli police in the West Bank are investigating a suspected arson Sunday of a home belonging to a key witness in the case of a Jewish terrorist attack that killed three Palestinians in the village of Duma in July of last year. Authorities suspect that assailants set fire to the home of the witness, who along with his wife managed to escape the blaze. They were, however, treated for smoke inhalation at a hospital in nearby Nablus.Palestinian sources reported on Sunday that large contingents of IDF troops and police investigators arrived at the scene and began collecting evidence. Palestinians say that the alleged assailants hurled petrol bombs into the home at around 2:00 a.m. on Sunday. The home is located just meters away from the house that was torched by suspected far-right Jewish terrorists.
