Two of the Tuesday assaults hit near Rafah and north of the city of Khan Yunis, near the border with Egypt, AFP reported, citing Palestinian security sources and witnesses.
Targets near the Zeitoun district, east of Gaza City, as well as the Deir al-Balah refugee camp in the centre of the impoverished territory were also hit during two other attacks.
Earlier in the day, security officials with the Palestinian resistance movement, Hamas, said six Israeli tanks had crossed into an area in the south of the coastal sliver, Reuters had reported.
The incursion reportedly saw one of the tanks firing shells at a house also in the proximities of Khan Yunis and an Israeli soldier piercing through the bordering security fence.
The Palestinians, in return, fired mortars toward the Israelis, wounding two soldiers.
On Monday, Israeli forces killed a Palestinian in the southern Gaza Strip, claiming they were heading off an attempted bomb attack near the enclave’s border with Israel.
The Israeli forces have been carrying out regular bloody forays into Gaza ever since the December 2008-January 2009 war, in which they killed over 1,400 Palestinians and caused over $1.6 billion in damage on the Gaza Strip’s economy.
Tel Aviv has imposed a strict blockade on Gaza for over three years now, depriving 1.5 million Gazans of food, medicine, fuel, and other necessities. The siege has also claimed the lives of hundreds of Palestinians.
