As it pushes for national gun control, the White House on Wednesday addressed a tragic shooting close to President Barack Obama's home in Chicago.

Fifteen-year-old Hadiya Pendleton, who last week performed at Obama's inaugural festivities, was killed when a gunman opened fire on a group of students just blocks from King College Prep and about a mile from Obama's home in Kenwood on the South Side.

Hadiya was hanging out with her volleyball team at Harsh Park after taking exams Tuesday afternoon. About a dozen teens had taken shelter under a canopy during a rainstorm when a boy or man jumped a fence in the park, ran toward them and opened fire around 2:20 p.m., police said.

Hadiya was wounded in the back and a 16-year-old boy -- also a student at King -- was shot in the leg, police said. The attacker got into an auto and fled, police said. No arrests have been reported.
