The strikes on the Gaza Strip come after Palestinians spent Thursday protesting against the USA government's decision to recognize Jerusalem as the Israeli capital.
Israeli media reported that the Israeli army fired the shells on an Islamic Hamas movement military post east of al-Mughazi Refugee camp in central Gaza Strip, in response to earlier rockets firing from Gaza into southern Israel.
Hamas leader Ismail Haniyeh called for a "Day of Rage" leading up to the protests.
The security situation in Israel and the Palestinian territories is febrile following US President Donald Trump's recognition of Jerusalem as the capital of Israel, which Palestinians see as a political and religious red line. In the blast and its aftermath, 12 members of the terrorist group were killed, along with two Hamas operatives.
Dozens of Palestinians in Gaza also staged violent protests along the security fence surrounding the coastal enclave, throwing rocks and rolling burning tires at the barrier and the Israeli soldiers on the other side.
