An 18-year-old construction worker braved rampaging floods in the Philippines to save more than 30 people, but ended up sacrificing his life in a last trip to rescue a baby girl and her mother who were being swept away on a styrofoam box.

Family members and people who Muelmar Magallanes saved have hailed the young man a hero, as his body lay in a coffin at a makeshift evacuation centre near their destroyed Manila riverside village.

"I am going to be forever grateful to Muelmar," said Menchie Penalosa, the mother of the six-month-old girl whom he carried to safety before being swept away himself. "He gave his life for my baby. I will never forget his sacrifice."
