A devastating, two-mile-wide tornado touched down near Oklahoma City on Monday, killing at least 51 people—including at least 20 children—decimating homes, businesses and a pair of elementary schools in the suburb of Moore.
According to the state’s medical examiner, the death toll was expected to rise.
The schools—Plaza Towers Elementary and Briarwood Elementary—were leveled by the tornado. It was unclear how many children were in them at the time the twister hit, but according to KFOR-TV, at least seven children died at Plaza Towers, and as many as two dozen more were feared to be trapped inside the rubble. An Associated Press photographer saw rescue workers pull several children out alive. A makeshift triage center was set up in the school’s parking lot.
