"In the last few days, a massive cyclone has ripped through the center of our nation, destroying nearly 90 percent of the city of Beira and all the surrounding villages," Heidi says in a video posted to Facebook.
The United Nations Food Agency has reported that the emergency is getting "bigger by the hour."
"People are absolutely desperate. Over a thousand people have lost their lives. There are bodies floating in the water. We sent a team before this cyclone hit from Iris Relief. They are on the ground ... being the hands and the feet and the heart of Lord right now in this crisis," Heidi says.
