Four Palestinians have been killed in clashes during an Israeli raid to arrest a suspect in the occupied West Bank, local sources say.
Israeli police said undercover forces came under fire after entering Jenin refugee camp to arrest the suspect from the Islamist militant group Hamas.
The Palestinian news agency Wafa said four Palestinian men were killed and that a fifth was seriously wounded.
It is one of the highest death tolls in West Bank violence for months.
The Israel Border Police said officers from an undercover unit "came under heavy fire from close range from a large number of terrorists" as they sought to arrest the suspect in the early hours of Monday.
The officers returned fire and "neutralised" the attackers, it added.
According to the Palestinian news agency Maan, the Israeli forces opened fire after setting an ambush.
