8. 1 dead, 2 hurt in US school shooting
A student at a high school in the US state of Maryland has shot 2 other students, seriously injuring them.
The 17-year-old shooter was shot dead by a school security officer.
Great Mills High School in St. Mary's County was on lockdown following the incident. One of the shooter's targets -- a 16-year-old female student -- was in critical condition, while the other -- a 14-year-old boy -- was described as stable.
The county sheriff said there was an indication that a prior relationship existed between the shooter and the female student. But he said it was too early to determine if that was a motive for the shooting.
The US has experienced a long series of school shootings. In February, a gunman killed 17 students and faculty in Florida, re-energizing a national debate over firearms. A nationwide rally for tougher gun control is planned for Saturday.
