The raid was to demolish the home of Ahmad Qanba, a Palestinian charged with aiding a Hamas cell in the West Bank, the army said.
It said Qanba had been part of a cell that carried out a January 2018 attack in which a rabbi was killed.
Heavy clashes broke out with young Palestinians throwing rocks at the Israeli troops, witnesses said.
The army said forces had "identified a number of armed terrorists who hurled explosive devices and fired towards them. The forces responded with riot dispersal means."
