GAZA CITY, Gaza Strip (AP) — A witness and Hamas media say that masked gunmen have killed seven suspected informants for Israel near a Gaza City mosque as worshippers were ending midday prayers.
The shootings brought the number of alleged collaborators killed in the coastal strip on Friday to 18.
Earlier in the day, Hamas killed 11 men by firing squad in Gaza City's police headquarters, according to the Hamas-run Al Rai website.
The killings came a day after Israel killed three top Hamas military commanders in an airstrike on a house in southern Gaza.
Friday's public shooting took place near the al-Omari Mosque in downtown Gaza.
A witness says masked gunmen lined up the seven men in a side street and opened fire on them. He spoke on condition of anonymity, fearing for his own safety.Associated Press
