Sirens sounded Sunday morning in the Gaza Belt, including in Yad Mordechai and Nativ Ha’asarah, just after 11:10 am. 

So far, no injuries nor damage are reported.

The IDF clarified after an initial investigation that the sirens were a false alarm, but that a rocket had been fired; it boomeranged back into Gaza. 

In recent weeks there have been several instances of rocket fire from Gaza, with a local Salafist group affiliated with Islamic State (ISIS) taking credit and threatening more attacks.

The group has been clashing with Hamas, and evidently sought to cause harm to Hamas by instigating a clash with Israel that would trigger retaliatory strikes.
