Ice storms have hit central parts of the US killing at least 21 people. About 300,000 homes have been left without power
The extreme weather has brought down trees, traffic lights and power lines which have led to blocked roads
Council workers have been chopping off branches hanging above icy power lines so that electricity supplies can be restored in Missouri and Oklahoma
Local people have also tried to clear heavy ice from the branches of trees hanging over their homes
Loads of roads and pavements are still covered in thick layers of ice
Ice storms happen when rain falls when the temperature is very low. It freezes almost as soon as it hits a surface
This winter has been very cold in America - and more bad weather is expected
