Flood waters have begun receding in Mozambique, and residents have started returning to the worst-hit city.

The United Nations Resident Coordinator for Mozambique, Jennifer Topping, visited the city of Chokwe on Wednesday to assess the needs. She says Mozambique will require help to get life back to normal.

The city of Chokwe was among the worst hit by flooding that displaced as many as 150,000 people. The U.N. says flood waters killed at least 38 people over the last several days.

The U.N. said this week at least $15 million would initially be needed in relief aid.
