The IDF shot and killed two Fatah gunmen in Nablus on Tuesday.
One of the operatives was killed on the spot, while the second died later of wounds he sustained.
Palestinian sources said the soldiers were part of an IDF undercover force.
The army reported that the soldiers had ordered the two gunmen to halt, at which point they tried to flee the scene. One of the gunmen, Adel Abu Reish, was responsible for carrying out shooting attacks and planting bombs in the area, the army said.
