Palestinian security sources and witnesses said Monday that factional infighting renewed on Monday in northern Gaza, mainly near the so-called Abraj Al-Awda residential buildings and in the vicinity of the civil defense premises.

Initial reports said some injuries have taken place in the area as infighting broke out there. No medical sources confirmed causalities.

Early on Monday morning, witnesses said that gunmen, believed to be members of the Hamas-formed executive force of the interior ministry and Ezzeldin Alqassam brigades of Hamas, attempted to place roadblocks around the house of local Al-Aqsa Brigades, an off-shot of Fatah, Samih Almadhoun.

Witnesses added that fellows of Almadhoun opened fire in the air to prevent Hama’s members from placing the roadblocks. No details were reported.

Both Hamas and Fatah agreed Sunday on their ninth ceasefire in recent months, trying to put an end to fierce gun battles that have claimed lives of 27 Palestinians and wounded more than 250 others since last Thursday.
