PHILADELPHIA (AP) - Authorities say a 14-year-old boy was critically wounded when he was shot in the back of the head as he was playing at a southwest Philadelphia schoolyard.

Police say the youth was among a group of people at W.C. Longstreth Elementary School city's Kingsessing neighborhood at about 7:15 p.m. Saturday when the gunman drove up and fired at least six shots.

Others in the group dragged the teen into the street and arriving officers rushed him to Penn Presbyterian Medical Center, where he was listed in critical condition.

Police say no arrests were immediately made and no weapon was recovered; it's unclear whether the teen was the intended target.
