RIYADH - A pregnant woman, her husband and infant daughter were among six Filipinos killed in a weekend fire at their Saudi Arabian residence, the Philippines embassy said on Monday. The blaze, blamed on an electrical overload, broke out just after 6:00 am (0300 GMT) Saturday at the apartment where three families lived in central Riyadh, Philippines charge d'affaires Iric Arribas told AFP. All three family members, including the 18-month-old daughter, died from smoke inhalation, he said. The father of a second family had just left for work when the building caretaker called to alert him to the blaze.
