A Palestinian infant was killed and several people injured when their home was set alight by Israeli settlers in the northern West Bank early Friday, dpa cited an official as saying. A group of masked people believed to be Israeli settlers threw flammable bombs into two houses on the outskirts of the village of Doma, south of Nablus, said Ghassan Daghlas, a Palestinian Authority official. In one house, the fire killed an 18-month-old boy and injured his parents and 4-year-old brother, who were taken to Rafidya hospital in Nablus, a medical source said. The injured were in a serious condition.
