The three were among seven small children pulled lifeless from the rubble of the Plaza Towers Elementary School after a monstrous tornado raked across the building, leaving the one-story building a heap of bricks, broken concrete and twisted metal. In all 24 people were killed — including 10 children — when Monday's storm ravaged Moore and a slice of Oklahoma City.

Landon McNeill, Angle's softball coach, lovingly called the charismatic kid "a pickle." He said he was with Sydney's parents Monday night as they waited at a church for news about their daughter. Her older sister, who was also at the school, made it out safely, and they held out hope that Sydney had ended up with someone else and would turn up.

"Sydney was real quirky," McNeill said. "She could be anywhere and have fun doing it."

The attack occurred in the southeast London neighborhood of Woolwich, just a few blocks from the Royal Artillery Barracks.

Two men reportedly attacked another man. Witnesses said the two men were shot by police and a number of weapons — including butchers' knives — could be seen on the street, which was splattered by blood.

French President Francois Hollande, speaking at a press conference in Paris with Cameron, said it was a British soldier who was killed. Cameron didn't immediately confirm that fact but the Britain's Ministry of Defense said it was urgently investigating the attack.

Cameron did say said there were "strong indications" it was a terrorist incident.

"We have suffered these attacks before, we have always beaten them back," Cameron said. "We will not be cowed, we will never buckle."

Live television images of the scene showed a trail of blood staining a pavement, cordoned off streets and crime scene investigators marking the scene.
