A videograb shows body of Palestininan boy lying on the road.

"The two children, Adam Samer Al Ghoul (8 years old) and Basil Suleiman Abu Al Wafa (15 years old), were shot dead by occupation forces in the city of Jenin," according to the Palestinian health ministry.

CCTV footage circulating online and on television news shows a boy being struck by a bullet and falling in the street, sending other children fleeing.

Other images show a teenager also being hit by a bullet and falling, then appearing to call for help as more shots hit the ground around him and other people run for cover. The teenager can be seen struggling on the ground in apparent agony for at least half a minute.

An official with the Palestinian Red Crescent told AFP that the boy and the teen had been on a side street of central Jenin's main thoroughfare, an area theoretically off limits to the Israeli military as it is under the sole control of the Palestinian Authority.

Hours later, WAFA said another two Palestinians, Muhammad Jamal Zubaidi and Wissam Ziad Hanoun from Jenin camp, were killed by the Israeli forces, adding that "the occupation forces took their bodies."
