The Israeli army killed a Palestinian youth during clashes with protesters in the occupied West Bank on Monday, the Palestinian Health Ministry said, prompting the United Nations to demand an investigation.

The ministry said in a statement that the citizen was shot live in the chest, and arrived in a very critical condition to the National Hospital in Hebron from al-Aroub refugee camp, where he was martyred.

Video footage circulated on social media showed that the occupation forces fired at the Palestinian youth Omar Haitham Badawi (22 years) without posing a threat to the soldiers.

Badawi was walking near his home in al-'Arroub refugee camp, north of Hebron. The video showed that he was talking to journalists when he was shot. He was pronounced dead at Al-Ahli Hospital in Hebron.

The UN special coordinator for the Middle East peace process, Nikolai Miladinov, was shocked by the video, saying in a tweet that the video showed that Badawi did not pose any threat to anyone.He called for an investigation into the incident and offered his condolences to the family of the martyr Badawi.

It is not clear whether the young Omar Badawi participated in the protests organized by Palestinians to commemorate the fifteenth anniversary of the departure of former Palestinian President Yasser Arafat through marches in all Palestinian governorates.

A spokeswoman for the Israeli army said troops were sent to al-'Arroub refugee camp in search of Palestinians who threw stones at cars and a nearby road, and that they opened fire when confronted with "a large number of rioters, some carrying incendiary bombs."
