A young boy had to have his leg amputated and his sister suffered shrapnel wounds to the face on Saturday after a mine exploded when they wandered onto an unmarked Israeli minefield in Syria's Golan Heights.
Guy and Tal Yuval, parents of Amit, 12, and Daniel, 11, were also injured in the blast.
The Israeli military, which illegally annexed the Golan Heights in 1981, insisted that the minefield was marked with signs.
But Daniel managed to tell doctors that "there was no fence where we were playing and we could enter with no problem."
A military spokesman admitted that some fences were in need of repair.
