The Israeli military shot and killed a Palestinian militant on Monday, as he attempted to escape arrest in the West Bank village of Al Fawwa, Palestinian witnesses and the army said.
A second militant was later detained by the Israeli military forces.
Witnesses said both men were members of the Al Aqsa Martyrs' Brigades, a violent off shoot of Palestinian leader Yasser Arafat's Fatah Party.
The Israeli army said the man, Ahmed Abu Mujahed, died as soldiers attempted to treat him.
His body was left in the area for Palestinian emergency services to collect in the early hours of Tuesday, once the operation was over.
It was then taken to the morgue at a hospital at Hebron, West Bank.
The Palestinian militants were believed to have been involved in terrorist activities in the West Bank.
Israeli security forces destroyed their equipment and cars that belonged to them.
