The Israeli army said it targeted four Hamas places in the Gaza Strip on Thursday after mortar shells were fired from the Palestinian enclave towards a nearby army position, according to AFP.

No injuries were reported on the Israeli or Palestinian side.

Due to the many armed groups in Gaza, it was unclear who was behind the mortar fire, but Israel blamed Hamas for all the incidents as it has controled the coastal enclave for the past 10 years.

"In response to the mortar shells fired at a military post adjacent to the northern Gaza Strip, (Israeli) tanks and (Israeli) aircraft targeted four Hamas military posts in the northern Gaza Strip," the Israeli army said in a statement.

Israel has waged three military cross-border attacks since Hamas took over Gaza 2007, leaving thousands killed and injured. Attacks like this are a regular occurance.

The incident comes as Hamas and its rival faction Fatah seek to pursue a historic reconciliation deal ending their 10-year-old feud.
