Armed Palestinian masked militants push back a crowd of worshippers outside a mosque in Gaza City after Friday prayers on August 22, 2014, before executing 18 men for allegedly helping Israel in its six-week assault on the Palestinian enclave. Six of them were grabbed from among hundreds of worshippers leaving the city's largest mosque, by men in the uniform of Hamas's military wing, the Ezzedine al-Qassam Brigades, witnesses told AFP.
