An IDF soldier was lightly wounded Thursday morning when a homemade grenade was thrown at a checkpoint in the flashpoint West Bank city of Hebron.
The attack took place at the Pharmacy checkpoint during a demonstration by Palestinians.
The soldier received medical care in the field.
No details are immediately available about the identity of the attacker or the soldier.
Hebron was recently in the center of a wave of violence, with near-daily stabbing attacks against soldiers and civilians, though tensions appear to have calmed in recent days.
On Wednesday morning, a Palestinian teen was arrested after approaching a Border Police post in the city with a knife.
IDF and Border Police forces arrested 17 Palestinian terror suspects throughout the West Bank late Wednesday, the army said.
One other Palestinian was arrested in the sweep, but the suspicions against him appear to be criminal.
One of the terror suspects is a Hamas activist, and several others are said by the army to be members of the Popular Front for the Liberation of Palestine terror group.
