Palestinian Resistance Movement, Hamas said it did not seek war with the Zionist entity but would resist incursions into the Palestinian enclave.
Three days of Israeli airstrikes and tank fire on Gaza have raised concerns of a new Israeli aggression.
Hamas leader in Gaza, Ismail Haniyeh, accused Israeli occupation forces of intruding nearly 200 meters into Gazan territory.
“We are not calling for a new war, but we will not under any circumstances accept these incursions,” he said in a Friday prayer sermon in the Gaza Strip.
Earlier in the day Israeli aircraft carried out their fourth air raid on the Palestinian enclave since Wednesday, attacking sites at Beit Lahiya in northern Gaza and near Khan Yunis in the south of the territory, witnesses said.
There were no reports of any casualties.
The Israeli army confirmed only one strike, saying it was a reaction to cross-border mortar fire.
On Thursday, Zeina Al-Amour, a 54-year-old Palestinian woman, became the first fatality of the flare-up after Israeli tank fire hit her home, medics said.
The violence has raised concerns for a ceasefire between the Israeli enemy and Hamas, that has held since the 50-day war in 2014 left 2,251 Palestinians and 73 Israelis dead.
