(Al Jazeera) – As paramedic Mazen Jabreel Hasna set out towards the field east of Gaza City with his medical team for the Friday demonstration, he had a sinking feeling it would be another bloody day for the unarmed Palestinian demonstrators. Hasna and his team were in a heightened state of alert, taking into consideration the high number of casualties during demonstrations in the weeks prior. As he got ready on April 27, he tried to stay positive by reciting verses of mercy from the Quran for extra protection. His gut feeling, however, turned out be an accurate predictor of the day’s events – only this time it was Hasna among the gravely wounded.
