“As the officer was waving, the men on the armored cars started shooting at that car,” Mohammed says. “And it wasn’t warning shots; they were shooting as in a battle. It was as though they were in a fighting field. I thought the police officer was killed. It was insane.” Officer Salman managed to dive out of the way as the bullets rained down. “I saw parts of the woman’s head flying in front of me,” recalled his colleague, Officer Sarhan Thiab. “They immediately opened heavy fire at us.”

That’s how the Nisour Square massacre began.
