Georgia, May 21 (AFP) - Exactly one month after the bloodbath at Columbine High School in Colorado, an apparently heart-broken teen opened fire on his fellow students at a high school in the southern US state of Georgia, injuring six classmates. The 15-year-old boy then put the gun in his mouth, but a school official gently talked him out of pulling the trigger. The boy then broke into a flood of tears and surrendered, witnesses said. Six students were injured in the Thursday incident, one seriously, hospital officials said. Two of the injured students were quickly released after treatment, they added. The gunman -- identified as a 15-year-old sophomore (grade 10 student) -- was reportedly distraught over having broken up with his girlfriend, one student reported. The shooting occurred Thursday just after 8:00 a.m. (1200 GMT) at Heritage High School, located in this bedroom community 32 kilometers (20 miles) east of Atlanta. The incident happened exactly one month after two teenage gunmen went on a shooting rampage on April 20 at Columbine High School in Littleton, Colorado, killing 15 including themselves. In the shooting rampage here "there were no fatal injuries, so everyone's going to be okay," a Rockdale County police spokeswoman told AFP. However one teenage girl was rushed to Grady Hospital in Atlanta with abdominal injuries where she underwent surgery, officials said. The teen gunman "has no prior record that I know of," said Jefferson County Sheriff Jeff Wigington. Police declined to reveal the boy's name because he is a juvenile -- but the Jefferson County prosecutor nevertheless said he would seek to charge the boy as an adult, local news media reported. The teen reportedly faces aggravated assault charges. Authorities said the youth was armed with a .22 caliber rifle with an altered stock as well as a handgun. The incident was ended in dramatic fashion by vice principal Cecil Brinkley, said senior (last-year student) Joe Wattz. "After he had done some of the shooting he put the gun in his mouth," Wattz said. "Then, Mr. Brinkley walked up to the kid and said, 'give me the gun.'" The boy handed him the gun and started crying, saying "Oh my God, I'm so scared." Brinkley took the boy in his arms, Wattz said. Nathanial Deeters, a 15-year-old student, said he spoke to the shooter before the spree began. He said the boy was upset about breaking up with his girlfriend three days earlier. Deeters turned around to talk to someone else when he heard what sounded like a cap gun going off behind him. It was the last day for seniors, a traditional time for pranks. "At first I thought it was a senior prank, then I turned around and saw a gun in his hand," he told AFP. "I yelled at him, 'Why are you doing this?'" "He pointed the gun at me, then he shot the kid next to me in the foot, Deeters said. "I grabbed the kid who was shot, and helped him run out the door with me ... It was a rampage. Kids were stampeding outside." "I talk to him every day. He didn't seem like a guy who would do this," said Deeters, who described the gunman as "not a very social person." The school's 1,000 students were quickly evacuated. Parents were asked to gather at another nearby location, and reporters were kept away. A team of federal agents from the US Bureau of Alcohol, Tobacco and Firearms (BATF) descended upon the school and scoured the buildings searching for weapons and explosives. Fearing they found a bomb, police exploded at least one knapsack -- which turned out to contain "just books and a calculator," Wigington said. US President Bill Clinton, who was in Colorado meeting with victims of last month's Columbine High massacre, was horrified when he heard of the Georgia rampage. The shooting came just hours before the US Senate approved new gun control measures introduced after the Littleton shooting as part of a juvenile justice package. Vice President Al Gore cast a rare tie-breaking vote to approve legislation that creates a new federal bureaucracy to monitor gun shows, and bar people who do not hold a federal firearm license to participate in them. The Senate also approved rules that require pawn shops to do background checks before completing all firearm transfers, including the return of guns to their owners. An opinion poll released Thursday showed that more Americans favor stricter gun laws. Two thirds of respondents (65 percent) said it is more important to limit gun possession than to protect the rights of gun owners, according to the Pew Research Center poll. --=-=--
