The Egyptian army cracked down with brutal force on a Nakba day protest in front of the Israeli Embassy in Cairo on May 15, 2011, firing teargas, rubber-coated steel bullets – and, some reported, live bullets – at protesters. More than 350 people were reported injured, while over 150 protesters were arrested pending military interrogation and trials, including prominent revolutionary youth reporting the events of the night on Twitter. Protesters as well as bystanders provided a gripping minute by minute narrative, complete with photos and videos, of the protests and the ensuing crackdown in the teargas filled streets of Cairo's Giza district. As news broke of the bloody response by Israel to the Nakba (‘Day of Catastrophe’, as it is known in the Arab world) protests at its borders with Lebanon, Syria and Gaza, protesters in downtown Cairo converged on the Israeli Embassy early in the afternoon. At one of the largest protests up to date by the Israeli embassy. Twitpic photo by Mosaab Elshamy. Political activist and revolutionary media icon Gigi Ibrahim (@Gsquare86), back from a world tour of the lecture and media circuit, posted a video on YouTube showing scores of protesters chanting while clinging to the embassy fence, as security forces were deploying in front of the building: The violence by security forces reportedly broke suddenly and unprovokedly, while protesters were demanding that the embassy flag be taken down: @mosaaberizing: Large group of CSF [paramilitary Central Security Forces] troops just arrived at the embassy. Met with angry chants. @3arabawy: csf pigs have fired tear gas and the army has shot in the air in front of israeli embassy in giza @Gsquare86: The peaceful protesters at the #IsraeliEmbassy in#Cairo are doing nothing to the embassy, why are they firing tear gas and shooting in air? @msheshtawy: First, people were just chanting, then some people removed the fence , but didn't enter or did ANYTHING to the army #israeliEmbassy cont. @msheshtawy: They just stood there , the army didn't do a thing, were standing peacefully , then suddenly the police came #israeliEmbassy Coverage quickly turned dramatic, reminiscent in tone of the 18 days of the revolution, as many protesters and journalists tweeted non-stop reports of the clashes and posted snapshots: Police moves back, we come forward, they fire tear gas, we run back and throw rocks.. Yfrog photo by Gigi Ibrahim @Gsquare86: People r regrouping ..morad st is a battle zone police holding machine guns and non stop firing @3arabawy: the firing of tear gas continues. Haven't seen as much fired since 28 jan @LeilZahra: Tear gas is still raining. It is unbelievable. We can hardly breath. #Egypt #jan25 #nakba #may15 @arwasm: Silent streets.

And it is not the bloody tear gas that we crave it's the adrenaline. Tarek Shalaby posted several poorly lit dramatic live videos on Bambuser, showing protesters recovering from teargas [ar], and shouting as bursts of gunfire are heard close by [ar]. Amr Salama also posted live videos on Bambuser, showing ambulance crews treating protesters [ar], and spent ammunition casings used by security forces [ar]. Gigi Ibrahim, Hossam Hamalawy, Mostafa Hussein and others published photosets of the clashes on Flickr and Purephoto. A video by Gigi Ibrahim on YouTube features impressive footage of protesters regrouping after the first teargas attack: Many protesters were injured or treated for respiratory problems caused by the heavy tear gas use by security forces. There were also multiple but unconfirmed reports of two possible fatalities: @tarekshalaby: Young men just dropped to the ground in front of me. Prolly just temporary breathing problem… @moftasa: From the ambulance radio: 4 cases suffocation. @tarekshalaby: We're by kintaaki [KFC, Mubarak propaganda had claimed it was feeding Tahrir revolutionaries]. How ironic! Ambulance staying put to treat the injured.
