GAZA - Hamas militants killed seven more Palestinians suspected of collaborating with Israel in a public execution in a central Gaza square on Friday, witnesses and a Hamas website said.

The victims, their heads covered and hands tied, were shot dead by masked gunmen dressed in black in front of a crowd of worshipers outside a mosque after prayers, witnesses and al-Majd, a pro-Hamas website, said.

Earlier on Friday, 11 people suspected of collaborating with Israel were killed by gunmen at an abandoned police station in Gaza, Hamas security officials said.
