Ynet reports: Hamas’ Deputy Politburo chief Mousa Abu Marzook posted a message on his Facebook page condemning the execution of six people accused of being Israel collaborators.

He demanded that those behind the act be tried. “The way these collaborators were killed and the images after their death are totally unacceptable and those responsible must be indicted. These events must never repeat themselves,” he wrote.

Abu Marzook further added, “We endorse punishments to spies and especially to those who took part in the death of our commander and undermine our resistance but they should only be punished by law.”

Palestinian gunmen shot dead six alleged collaborators in the Gaza Strip who “were caught red-handed,” according to a security source quoted by Hamas’ Aqsa radio on Tuesday.
