No duds were found as of yet. No injuries or damage were reported. The IDF is canvassing mountains near the city.
Three months ago, loud blasts were heard in the city. Security forces estimated rockets had been fired at the city from Sinai. Last April, a rocket fired from Sinai landed between two residential buildings.
Earlier on Sunday, an air raid siren sounded in Tel Aviv for the second time. An Iron Dome battery intercepted the Fajr rocket fired from Gaza.
Hamas said that the firing was an act of revenge for the "murder of the children in Gaza."
The group was referring to the death of at least four children and five women in an Air Force strike aimed against Yahia Rabia, a high-ranking official in Hamas' rocket unit.
The army bombed his home but it is unclear whether Rabia was at home at the time of the strike.
Constant rocket barrages have been fired at southern communities including Ashdod, Ashkelon, Beersheba, Beer Tuvia and Eshkol since Sunday morning.
Grad shrapnel hit a vehicle in Ofakim earlier in the day leaving five people wounded.
