Gaza - A member of Palestinian President Mahmoud Abbas' Fatah movement was shot and killed early Saturday in the northern Gaza Strip, sources said.

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.
