Two Palestinian intelligence officers have been killed by Israeli special forces during a raid in the occupied West Bank, Palestinian officials say.
The Israeli forces, some undercover, entered Jenin overnight to arrest two Palestinians suspected of recent attacks, according to Israeli media.
The Palestinian officers were shot dead after they witnessed the raid and reportedly opened fire at the Israelis.
A Palestinian man identified as one of the suspects was also killed.
The West Bank-based Palestinian Authority (PA) co-ordinates security with Israel and clashes between their forces during such operations are rare.
