The IDF used a drone to attack a terror operations room in the West Bank city of Tulkarm, the military stated on Monday.
The strike was conducted in the Nur al-Shams refugee camp.
Five individuals were killed in the strike.
General strike planned in response
Four loud explosions were heard after an Israeli drone targeted a house in the camp, Palestinian Authority-run news agency, Wafa, reported.
The Hamas-affiliated Safa News said general strikes were planned in the area in response to the events.
On Tuesday, Wafa claimed four people had been arrested in Hebron.
