Hamas movement held Fatah responsible for what it called the "security violations" committed in the Gaza Strip.
Hamas spokesman Sami Abu Zuhri said on Wednesday that the violations came as part of the internal conflict in the Fatah faction on elections.
Earlier, a group called "Protectors of Legitimacy Against Illegal Dahlan Gangs" in Gaza fanned a statement saying it will fight "Dahlan and his gang."
Hamas described the group as an internal issue that should not be directed to the strip.
The spokesman accused Fatah of setting plots to destabilize and spread chaos in the strip.
