Ahmed Abu Ar-Rish Brigades, one of Fatah's armed wings active in southern Gaza Strip, said in a leaflet that it will not accept to be recruited in the Hamas-led security apparatus.

The Fatah wing said that the rejection was made after its members believe that the security issue is the job of security apparatus but not that of the gunmen, who are committed to battles against occupation.

Interior Minister Saeed Seyam announced on Thursday that his ministry will recruit 4,000 militants from different groups to form a special security executive apparatus in a bid to restore order and law in the Palestinian territories.

However, the decision was vetoed by Palestinian President Mahmoud Abbas on Friday, terming it as "illegal and against the constitutional rules".

Abbas had issued a decree to annul the decision.

Disputes over the new security branch came as a latest show of power struggle between Abbas and Hamas, which took office in late March following its victory over Abbas-led Fatah in a January Palestinian election.
