KAFR YASIF, Israel — Nabil Safiya had taken a break from studying for a biology exam to meet a cousin at a pizza parlor when a gunman on a motorcycle rode past and fired, killing the 15-year-old as he sat in a black Renault.
The shooting — which police later said was a case of mistaken identity — stunned his hometown of Kafr Yasif, long besieged, like many Palestinian towns in Israel, by a wave of gang violence and family feuds.
''There is no set time for the gunfire anymore,'' said Nabil's father, Ashraf Safiya. ''They can kill you in school, they can kill you in the street, they can kill you in the football stadium.''
The violence plaguing Israel's Arab minority has become an inescapable part of daily life. Activists have long accused authorities of failing to address the issue and say that sense has deepened under Israel's current far-right government.
One out of every five citizens in Israel is Palestinian. The rate of crime-related killings among them is more than 22 times higher than that for Jewish Israelis, while arrest and indictment rates for those crimes are far lower. Critics cite the disparities as evidence of entrenched discrimination and neglect.
A growing number of demonstrations are sweeping Israel. Thousands marched in Tel Aviv late Saturday to demand action, while Arab communities have gone on strike, closing shops and schools.
In November, after Nabil was gunned down, residents marched through the streets, students boycotted their classes and the Safiya family turned their home into a shrine with pictures and posters of Nabil.
The outrage had as much to do with what happened as with how often it keeps happening.
