A member of Palestinian President Mahmoud Abbas' Fatah movement was shot and killed early Saturday in the northern Gaza Strip, reported dpa.
According to witnesses, a group of militants in the early morning attacked the house of Abdel Salam Abu Taqia, 23, near Jabaliya refugee camp and killed him.
Hours later, the Hamas-controlled Interior Ministry said the murderer was arrested, and claimed the incident was motivated by family differences.
Abu Taqia was a member of the pro-Abbas naval police until Hamas routed all forces loyal to Abbas and took control of Gaza Strip.
Several members of Fatah and pro-Abbas forces have been killed in mysterious incidents in Gaza Strip following the Hamas takeover.
Fatah and Hamas exchange accusations over cracking down on each other's supporters in the Gaza Strip and the Fatah-dominated West Bank. dpa sar mga
