Three Palestinians children were killed and 11 others wounded Tuesday evening in an Israeli airstrike on a car north of Gaza City, medics said.
  
Joma'a Saqqa, chief of emergency at Shiffa Hospital in Gaza City, said that a six-year-old boy, a five-year-old girl and a 15-year-old boy were killed in the airstrike and 11 others injured.
  
He said that of the injured, three children were in critical condition and the rest sustained moderate injury.
  
Palestinian witnesses said that an Israeli drone fired at least one air-to-surface missile at a car that drove on a road between Gaza and the town of Jabalya, adding that those who were in the car managed to jump out of the car and ran away.
  
They added that the missile directly hit the car, and its shrapnel hit 14 people, most of them children.
  
Palestinian security sources said that the three militants in the car were members of the al-Aqsa Brigades, the Fatah movement's armed wing.
  
An Israeli army spokesman told Israel Radio that the Israeli air forces targeted a group of Palestinian militants involved in firing homemade rockets at Israel.
  
The airstrike came shortly after the Israeli Defense Ministry decided to carry out tough measures against Palestinian militant groups which fire homemade rockets at towns in southern Israel.
