Israeli forces launched a large military operation on Sunday night in Jenin in the northern West Bank.
In a statement posted to Telegram, the Israeli Defense Forces (IDF) said it launched an "extensive counterterrorism effort in the area of the city of Jenin and the Jenin Camp," striking "terrorist infrastructure."
The Palestinian Health Ministry said Israeli forces killed at least three people and injured 13 others in Jenin early Monday. Residents in Jenin told CNN they could hear sounds of explosions and heavy gunfire in the area.
Video from the scene showed wounded Palestinians being evacuated by ambulance to Jenin Government Hospital.
The IDF said it struck a joint operational command center for the Jenin Camp and operatives of the Jenin Brigade, a Palestinian militant group associated with Islamic Jihad.
"The operational command center also served as an advanced observation and reconnaissance center, a place where armed terrorists would gather before and after terrorist activities," the IDF said, adding that the camp was a "site for weapons and explosives" and "hub for coordination and communication among the terrorists."
"Additionally, the command center provided shelter for wanted individuals involved in carrying out terror attacks in recent months in the area," it said.
Palestinian Islamic Jihad said it will face its enemy "with all possible retaliation options," in response to the Israeli operations in Jenin.
"The aggression on Jenin will not achieve its targets, Jenin will not surrender. We will face the enemy with all possible retaliation options in response to the enemy aggression on Jenin," the militant group posted to its official Telegram channel.
The raid comes less than two weeks after an Israeli military raid on Jenin erupted into a massive firefight, leaving at least five Palestinians dead and dozens wounded. Eight Israeli troops were injured and successfully evacuated, according to the IDF.
