A preventive security officer and a 13 years old child have been severely injured on Sunday when unknown armed men opened fire at them in the Beach Camp, western Gaza. Medical sources said the child is in serious condition and undergoing surgery after his kidney and right lung stopped working due to the bullet he received. The officer was meanwhile shot in the right thigh in a separate attack as he was leaving his camp home. Eyewitnesses said ten unknown armed men nabbed the officer's weapon and a telecommunication device before escaping the scene.This is the seventh such incident this week on preventive security officers. Many officers working in Jebalia Camp northern Gaza were attacked with bombs planted in front of their homes. Another explosion took place a few days ago close to an officer's house in Jebalia Camp where a Martyrs brigade militant aborted an attempt to plant a bomb targeting another officer.
