10-year-old Saddam Rajab lived with his father, Iyad, in a studio apartment in the West Bank city of Tulkarem.

In january, the two were sitting on the roof with friends. Saddam asked for his father’s phone and took it downstairs, stepping outside.

Security footage obtained by the Associated Press shows what happened next.

Saddam died from his injuries 10 days later.

Israeli gunfire has killed at least 18 children under the age of 15 in the occupied West Bank this year, according to the United Nations.

Some were killed during Israeli military raids, others by sniper fire in peaceful areas.

The killings have risen as the Israeli military has stepped up operations.

The military told the ap that its rules of engagement “strictly prohibit intentional fire” at civilians, calling claims it targets minors “false” and “baseless.”

It said it had launched investigations into some cases. But it gave no word that any soldiers have been disciplined.

14-year-old Amer Rabee, an American-Palestinian teenager born in New Jersey, was also killed this year.

His father says he was picking almonds with friends, on a West Bank hilltop in the village of Turmus Ayya, when he was shot.

A security camera captured the sound of 36 gunshots.

And the military says it still investigating the death of two-year-old Layla, who was killed when an Israeli sniper fired through the second-floor window of her family's home.

The Israeli military said it is still investigating Layla’s case and could not give further details.
