In the predawn hours of May 28, Israeli soldiers operating in the village of Jit near Qalqilya in the West Bank shot dead a Palestinian man, Jassem al-Siddeh.

According to the military, soldiers had opened fire and “neutralized a terrorist” after he “tried to attack the force with a sharp object and posed a threat.”

But al-Siddeh’s family contends that the 19-year-old was shot dead as he slept in his bed. Relatives told The Times of Israel that after the shooting, soldiers argued among themselves, indicating that they themselves did not understand why one of them had opened fire.

Jassem’s brother Darwish al-Siddeh told The Times of Israel that the two of them and their father were the only ones at home when five soldiers came through the door at around 1:35 a.m.

“They entered, didn’t speak to anyone, and went straight into the room where Jassem was sleeping,” he said. “I heard heavy gunfire. It happened in minutes.”

From the next room, al-Siddeh said, he heard the soldiers begin arguing following the gunfire.

“One of them said in Hebrew, ‘What are you doing, are you crazy?’ I didn’t hear Jassem’s voice before the shooting – not a word. He was still asleep,” he said.

According to the Haaretz daily, al-Siddeh’s father Ibrahim also said he recalled hearing soldiers call the alleged shooter “crazy” as they ordered Ibrahim into an adjacent apartment, which belonged to another son.

Darwish said that after the shooting, the soldiers told the family to call an ambulance but did not allow them to enter the room where Jassem had been shot.

The soldiers did not ask for names or identification papers, he said, only telling them, “Sit down, the ambulance will arrive in 10 minutes.”

While they waited for the ambulance, the soldiers asked about other residents in the apartment building. Al-Siddeh said he answered their questions about their neighbors’ identity, though the soldiers did not enter other homes or arrest anybody in the building.

It was unclear why soldiers had raided the building in the first place. Jassem had no criminal record and nobody in the family was known to have been wanted by Israeli authorities, Haaretz reported.

According to Darwish, soldiers eventually took Jassem outside to a military jeep and then handed him over to a Red Crescent ambulance, al-Siddeh said. He was taken to a Palestinian hospital, where he was pronounced dead.

According to the al-Siddeh family, they were told by the hospital that Jassem had been shot twice in the chest. They also saw a video of Jassem’s body showing him bleeding from the chest.

Once allowed back in the room where Jassem was shot, the family took pictures showing blood on and under his bed. Four bullet casings were found as well.

The Israel Defense Forces says the incident is under investigation.
