Two people have been wounded, including a 14-year-old student, in another U.S. school shooting, this time in Atlanta, Georgia.
Police say the second victim is a teacher at Price Middle School and say one person, another student, was arrested. Other details were not immediately available.
The shooting comes as the U.S. Senate considers President Barack Obama's proposals for tighter gun laws. They include reviving the expired ban on military-style assault weapons and deeper background checks for gun buyers.
Gun violence has become a major issue in the United States since the December massacre of 20 young children and six staff members in a Connecticut elementary school by a mentally-deranged gunman.
