A group of Palestinians threw rocks at an IDF soldier, lightly wounding him, during an early Monday morning operation in the Aqabat Jaber refugee camp, near Jericho, the army said.
The soldier was taken to a hospital and was released back to his unit a short while later, the army said.
No arrests were made in the Palestinian refugee camp.
Overnight, the IDF seized two guns in Palestinian villages, one in Beit Sahour and the second in Yatta, a suburb of Hebron that has been the hometown of several terrorists who carried out attacks in the past two years, the army said.
The weapon found in Beit Sahour was a hunting rifle, an IDF spokesperson said.
The firearm found in Yatta was a Carlo-style submachine gun, a type of firearm that is prevalent in the West Bank due to its comparative low cost and ease of manufacture.
In late 2015, the IDF launched an operation to crack down on this type of gun and has since raided dozens of workshops suspected of manufacturing them, arrested weapons dealers and seized hundreds of Carlos.
The army handed the two guns found on Monday over to the police and Shin Bet security service for further investigation.
Elsewhere in the West Bank, the IDF also arrested 12 Palestinians suspected of rock throwing or taking part in violent demonstrations against Israeli security forces, the army said.
The suspects were handed over to the police and Shin Bet for questioning, the army said.
