The youth Ahmad Nassr Jarrar was shot dead by IOF on Tuesday morning after over three weeks of manhunt.
A Fatah spokesman, Osama Qawassmeh, said that death of Jarrar, who was killed in a shootout with the IDF, was "a type of field execution" and an Israeli "crime" that violated global law.
"An M-16 assault rifle and a bag containing explosives were found near his body", it said.
Hamas's armed wing, the Ezzedine al-Qassam Brigades, claimed Jarrar as a member and welcomed the January 9 attack in which Shevach was shot dead in what Israeli media said was a hail of 22 bullets.
During the raid, Israeli forces reportedly called on Jarrar to exit the building in which he was hiding, and when he did not, forces launched at least one missile at the building. Eyewitnesses at the scene told Haaretz that soldiers surrounded a house belonging to El-Hakim's father, a Palestinian from Nablus.
