The barrier has generated frequent protests by Palestinians
Israeli troops have shot dead a Palestinian man during a protest over the barrier Israel is building through the West Bank, Palestinian sources say.
They say the man, named as Aqel Srour, was hit in the chest by what appeared to have been live fire.
The Israeli army said troops opened fire when protesters threw stones at them, but declined to say whether live ammunition was used.
The protest, the latest in a series, took place near the village of Nilin.
Activists say Israel is taking 25 hectares (62 acres) of land from villagers to erect the barrier, which Israel says it is building for security reasons.
The Israeli army is also replacing the main access road to the village with a tunnel, to be controlled by the military.
Palestinians and their supporters say the plan will, in effect, turn Nilin into a "prison".
A Palestinian was shot and killed by Israeli forces today while protesting the separation wall in the West Bank village of Nilin. Another protester, who is 15, was wounded. 

Aqel Srur, who was 35, died in an ambulance while en route to a local hospital. He had been fatally shot once in the heart. Palestinians were fired upon by Israeli forces after they began to throw stones at the soldiers. Palestinian officials say Srur was shot once with a single round of live ammunition, something an Israeli Defense Force (IDF) spokesperson could not confirm.

According to the spokesperson, the IDF used "riot dispersal means," which included metal bullets coated with rubber and tear gas.

Srur was protesting Israel's separation barrier, which spans 723km and surrounds West Bank cities, separating them from one another. Israel says the separation walls are needed for security reasons, but Palestinians say it turns their villages into prisons. 

Palestinian and international activists have gathered almost every Friday for the last two years to protest the separation barrier in Nilin. In many cases the protests end with violence. In April, Basem Abu Rahmeh, age 30 was shot and killed by Israeli forces, also while protesting the Israeli separation wall in Bilin.

Construction of the wall began in 2002 and is set to surround the West Bank which was annexed by Israel in 1967. In 2004 it was deemed illegal by the International Court of Justice.
