( CNN ) -- Clashes between security forces and protesters left 15 people dead across Syria on Saturday , an activist group said Sunday . The deaths included eight in Homs and three in Daraa , said Rami Abdulrahman , the head of the Syrian Observatory for Human Rights . The report came days after Syrian security forces barged into a hospital and snatched 18 wounded patients , including five from an operating room , the Human Rights Watch reported , citing witness accounts . That event occurred Wednesday at al-Barr hospital in the western city of Homs during a major military operation . Human Rights Watch also reported that security forces had prevented medical personnel from reaching wounded people in several Homs neighborhoods . Days after the hospital raid , demonstrators took to the streets Friday , leaving 11 people dead across the country , said the Local Coordination Committees of Syria , an opposition group that documents and organizes protests . Human Rights Watch said Syria 's actions violate its obligation `` to respect and protect the right to life and the right to health and not to subject anyone to inhuman treatment . '' `` Snatching wounded people from the operating room is inhumane and illegal , not to mention life-threatening , '' said Sarah Leah Whitson , Middle East director at Human Rights Watch . `` Cutting people off from essential medical care causes grave suffering and perhaps irreparable harm . '' A doctor at al-Barr hospital said security forces beat people as they moved the wounded from the hospital . The actions stirred panic and prompted families to remove patients who they thought might be detained , the doctor told Human Rights Watch . `` They were looking for a specific person called Bilal . The administrator told them that there had been a Bilal who arrived at the hospital , but he had died from his wounds and his family had already taken the body , '' the doctor said . `` The security forces then asked the administration for lists of wounded who had arrived that day , and then I saw them go through the rooms of the hospitals taking anyone with a bullet wound , regardless of when they had arrived . In total , they took 18 wounded from the hospital . Five of them were taken from the operating room , including two who were still unconscious . '' Human Rights Watch said it has documented a pattern of security forces preventing medical personnel from getting to wounded protesters . Another doctor told the organization he went to Bab Dreib , a neighborhood where physicians were needed , but it was a challenge to get wounded people to a hospital because regime snipers were firing on cars . `` The situation was very dramatic . Five of the wounded had bullets in their stomachs and required hospitalization , but I could not get them to any hospital , '' the doctor said . Red Crescent volunteers in Homs said security forces prevented them from getting to some of the wounded . CNN can not independently confirm these reports . The Syrian government has repeatedly refused international journalists permission to report inside the country .
