"The Dens of Lions," a Palestinian umbrella group formed of militants from different factions, said one of the dead gunmen also worked for the security services of the Palestinian Authority (PA), which exercises limited self-rule in the West Bank under interim peace deals with Israel from the early 1990s.

The Dens of Lions identified a second man killed in Jenin on Wednesday (September 28) as the brother of a Palestinian who shot dead three people in Tel Aviv in April - among a series of street attacks within Israel that triggered its intensified West Bank raids.

A third gunman was killed by the Israeli forces in Jenin on Wednesday (September 28), the Dens of Lions said. The Israeli police statement said commandos had traded fire with other gunmen.
