(CNN) -- Israeli soldiers shot and killed a 22-year-old shepherd near the Erez crossing point in Gaza on Thursday, according to Palestinian medical officials.
Three Palestinians also were injured by gunfire in the same area, medical officials said.
Israel Defense Forces would only confirm that soldiers fired on two Palestinians who were seen in a 300-meter (984-foot) restricted "no-go" zone near the crossing. Both were hit below the waist, according to IDF.
The shepherd died Thursday night after getting shot in the spine earlier in the day, Palestinian medical officials said.
The medical officials also said three teenage boys out collecting stones Thursday were injured by gunfire in separate incidents in the same area as the fatal shooting. A 14-year-old boy was shot in the head. Another victim, 18, was shot in the leg. A third victim, 19 was shot in the arm.
Medical officials said 13 Palestinians have died and more than 30 have been injured this month.
According to Defence for Children International, an international human rights organization, in 63 percent of these cases, the people who were shot said the incidents occurred when they were working on or outside the 300-meter exclusion zone imposed by the Israeli army around Gaza.
