Funeral held for Palestinians killed in West Bank

STORY: Two of the dead were identified as members of the "Den of Lions," a group of Nablus gunmen with loose factional affiliations, which has grown over the past year and been involved in repeated clashes with Israeli forces.

A sixth man was killed in a separate clash near the West Bank town of Nabi Saleh near Ramallah.

Palestinian health officials said at least 20 people, including some gunmen and members of the Palestinian security forces were also wounded in Nablus, which has been at the center of violent clashes in recent months.

More than 100 Palestinians from the West Bank have been killed this year, most since late March during a crackdown that followed a string of fatal street attacks by Palestinians in Israel which killed 19 people.

Since then four members of Israel's security forces have been killed, an Israeli military official said, including at least one killed by the Den of Lions.
