At least 21 people were killed after ferocious storms and tornadoes tore down buildings and causing mass destruction in the southern United States.

Hundreds others were injured.

Most of the deaths occurred on Sunday after tornadoes hit Arkansas and other states.

Monday’s twister in Tupelo, one of several to tear across Mississippi, damaged hundreds of homes and businesses, downed power lines and tore up trees, the National Weather Service said.

After the Monday’s tornado in Tulopo, officials imposed an 8 p.m. (0100 GMT) curfew and in some residential areas were closed off as emergency crews checked downed power lines and gas leaks.

The storm system later pushed into parts of Alabama, where emergency officials said at least two people were killed at a trailer park near Athens, Alabama. 

Arkansas Governor Mike Beebe said at least 15 people had died statewide in the storm. 

Nine of the victims on Sunday came from the same street in Vilonia, a town with a population of about 4,100.

State authorities reported that one person was killed in Oklahoma, one in Iowa and another one in Kansas,

The National Weather Service said the threat of tornadoes will last for several days as a strong weather system interacts with a large area of unstable air across the central and southern United States.

According to AP News, The National Weather Service posted tornado watches and warnings around Mississippi, Tennessee, Alabama and Georgia that were in effect through Monday night.

Here are some photos of the aftermath…

Tornado is a natural disaster that sucked up things along its path and dropped them back to the ground may be a few meters away.

I first learned about tornadoes after reading the book, ‘The Wizard of Oz’.

I was 4 years old at that time and I wondered why only Dorothy’s house was sucked up by the twister and not some other things around it.

Actually tornado only destroys things along its path.
