Tornado

CHICAGO, April 21 -- Abarrage of tornadoes swept through Northern Illinois and Chicago late Friday, killing at least 50 people and injuring more than 1000.

The tornadoes inflicted heavy fatalities in Oak Lawn, a southwestern suburb and in Belvidere, 65 miles northwest of Chicago. One person was killed in Chicago and another in suburban Stone Park.

The twisters apparently struck the Chicago area without warning. Several students were killed in Belvidere as they were boarding buses in a high school parking lot. A number of the dead in Oak Lawn had been out roller skating when the tornado struck.
