The student says she had to climb over a school fence to flee the shooting which killed five teachers.

On Friday morning, as the final classes of the week were under way, panicked students began streaming out of a prestigious school just outside Bangkok. Inside, police say, a 14-year-old boy had opened fire at the Debsirin School in Nonthaburi, on the outskirts of the Thai capital. "I was standing in front of the teacher when she was shot," a shaken seventh grader tells the BBC, near the school gates. "She was talking to me when (the gunman) showed up." Still in her uniform, with her mother by her side, she explains how the shooter stalked from room to room. Police say he killed five teachers and injured more than a dozen people - including pupils - before turning the weapon on himself. Earlier, he had gunned down his grandparents. "I had to climb over the school fence to escape with other friends," the girl - who the BBC is not naming - continues. Her mother says the girl thought she might die. "[She said] 'I thought I'd never see you again'." Metres from the school gates, paramedics loaded the wounded into ambulances and rushed them to hospital, as milling crowds hugged and cried.
