Tahrir Triage // 15 Photos

In the last weeks of November, 2011, Cairo's Tahrir Square saw pitched battles between riot police and protesters, the protesters demanding an immediate end to military rule in Egypt.

Over 40 protesters were killed and more than 2000 injured during the clashes, where rocks and molotov cocktails thrown by activists were met by rubber bullets, high-speed tear gas canisters and in some cases, live rounds, by Egypt's notorious riot police.

In the melee, at least five triage units were set up in and around Tahrir Square. Mosques, fast food restaurants and the stoop of a travel agent soon became emergency field hospitals, prepped with skills and supplies for battlefield triage.

Doctors and emergency first aiders treated the wounded, who came in waves suffering from severe tear gas inhalation, head injuries, broken limbs and bullet wounds.

This series of pictures shows the work of volunteer doctors and first-aiders in and around triage units, field hospitals and the front line in Tahrir Square in November 2011.
