美国有线新闻 CNN 哥伦比亚发生严重泥石流 伤亡达数百人（在线收听）

Today's show begins in South America, where a deadly natural disaster has hit the nation of Colombia. It started in rain, torrential rain on Friday night. That caused three rivers to overflow around the city of Mocoa.

It's located in the southwestern part of Colombia and the flooding washed a stream of mud into Mocoa. Many people were sleeping when the mudslide came. Other witnesses said it was moving so fast, they had to run for their lives.

Colombia officials say more than 200 people were killed and hundreds more injured. But Colombia's president expected those numbers to increase as rescuers search for survivors. More than 1,000 soldiers and police officers are involved in that effort.

They say that 80 percent of the roads around the area have problems. So, it's hard to get to people who might be trapped. Rescuers are racing against the clock with more than 100 people still missing.

In 2015, rain in Colombia's northwest caused a mudslide that killed more than 80 people. Scientists say heavy rain, lots of deforestation, poorly made homes and dense populations can all put residents at risk.
