MAPUTO, Mozambique — The United Nations says the death toll from the flooding in Mozambique has risen by seven to at least 55 people.

The United Nations said Thursday that heavy rains in northern and central Mozambique have displaced 19,000 more people, raising the total number of displaced by floods the past two weeks to nearly 170,000.

The Mozambican government said there is a shortage of food for flood victims in southern Mozambique. Luis Nhala, a health official, said that residents are eating food that has mixed with contaminated flood water, which is resulting in cases of diarrhea and vomiting.

Mozambican state television showed children in need of food and water.

One man held an empty plate and told the camera: "Look, we are starving. The government must do something."
