Ma'an -- Hamas-backed police were deployed heavily in the Gaza Strip on Thursday, days after explosions rocked one Gaza neighborhood.Policemen were seen stopping cars, searching them and inspecting the ID cards of commuters, especially on the roads linking the Gaza's north and south.
The police announced the deployment a day in advance calling it a campaign to preserve law and order.
The explosions took place in the Ansar neighborhood of Gaza City, not far from a de facto government security compound.
No one has claimed responsibility for the blasts, which the de facto government said it was investigating.
The explosions followed threats by a radical Salafi Islamic group to retaliate for the death of its leader and its fighters in a shootout with Hamas forces in August.
The firefight in the city of Rafah, with the ultra-Islamist group Jund Ansar Allah left 24 people dead. The battle took place after an imam affiliated with the group challenged Hamas' authority, threatening to set up an "Islamic emirate."
