Fire engulfed a crowded squatters' area in Manila on the eve of Fire Prevention Month, leaving about 2,000 families homeless in the biggest blaze in the Philippine capital since 1978. Police said six people were injured and a 2-year-old boy was missing and feared dead. Witnesses said about six blocks in the Paco area were engulfed by flames. The cause of the fire was not immediately known. Police said it was the worst blaze since one in 1978 in a slum area of the Tondo district.
