MENA, Ark. Authorities began a house-to-house search today to check on residents after a tornado struck a "direct hit" on this mountain community, killing at least three people, injuring at least 30 others and flattening homes and businesses.

The twister descended quickly on Mena shortly after 8 p.m. Thursday after a series of siren blasts warned residents of tornadoes in the area.

Daylight exposed a community ripped apart. Century-old pecan trees leaned into homes some with pink insulation strung from their limbs. Along some streets, roofs had collapsed into homes. On other streets, roofs were simply gone.

"It just looks like a war zone," Mayor George McKee said.

Thurman Allen, 79, said his charitable group, the Order of the Eastern Star, had just sat down for its twice-monthly meeting at the Masonic lodge when the last siren sounded. Before the 19 attendees could take cover, the tornado peeled away the roof with winds so strong that some women had their shoes ripped off their feet.

"I was down on the floor I just flattened," Allen said.

One woman was killed by falling debris her body recovered after emergency workers cut part of the roof away.

Another person died in another roof collapse, while the third person was found dead in her front yard.
