Over 200 dead in Congo mine collapse

A very sad accident happened in a place called Rubaya in Congo.

A mine where people dig for a special metal called coltan collapsed, and more than 200 people died.

These people included miners, children, and women who sell things in the market.

Some people were saved but are hurt badly.

The mine is very important because it gives 15% of the world's coltan, which is used in phones, computers, and other things.

The area is controlled by a group called M23, who are rebels fighting the government.

Some people say M23 takes the minerals to get money for their fighting, and they are helped by the country next door, Rwanda.

Rwanda says this is not true.

The rebels want to take over the government and protect a group of people called Congolese Tutsi.
